The tiger (Panthera tigris) is a member of the genus Panthera and the largest living cat species native to Asia. It has a powerful, muscular body with a large head and paws, a long tail, and orange fur with black, mostly vertical stripes. It is traditionally classified into nine recentsubspecies, though some recognise only two subspecies, mainland Asian tigers and island tigers of the Sunda Islands.
Since the early 20th century, tiger populations have lost at least 93% of their historic range and are locally extinct in West and Central Asia, in large areas of China, and on the islands of Java and Bali. Today, the tiger's range is severely fragmented. It is listed as Endangered on the IUCN Red List of Threatened Species, as its range is thought to have declined by 53% to 68% since the late 1990s. Major reasons for this decline are habitat destruction and fragmentation due to deforestation, poaching for fur, and the illegal trade of tiger body parts for medicinal purposes. Tigers are also victims of human–wildlife conflict as they attack and prey on livestock in areas where natural prey is scarce.
The tiger is legally protected in all range countries. National conservation measures consist of action plans, anti-poaching patrols and schemes for monitoring tiger populations. In several range countries, wildlife corridors have been established and tiger reintroduction is planned..
The tiger is among the most popular of the world's charismatic megafauna. It has been kept in captivity since ancient times and has been trained to perform in circuses and other entertainment shows. The tiger featured prominently in the ancient mythology and folklore of cultures throughout its historic range and has continued to appear in culture worldwide.
The Old Englishtigras derives from Old Frenchtigre, from Latintigris, which was a borrowing from Classical Greekτίγρις 'tigris'.[4]
Since ancient times, the word tigris has been suggested to originate from the Armenian or Persian word for 'arrow', which may also be the origin of the name for the river Tigris.[5][6] However, today, the connection between the animal and the river is doubted, and they are likely to be homonyms.[6]
Nine recent tiger subspecies have been proposed between the early 19th and early 21st centuries, the Bengal, Malayan, Indochinese, South China, Siberian, Caspian, Javan, Bali and Sumatran tigers.[9][10] The validity of several tiger subspecies was questioned in 1999 as most putative subspecies were distinguished on the basis of fur length and colouration, striping patterns and body size of specimens in natural history museum collections that are not necessarily representative for the entire population, it was proposed to recognise only two tiger subspecies as valid, namely P. t. tigris in mainland Asia and the smaller P. t. sondaica in the Greater Sunda Islands.[11]
This two-subspecies proposal was reaffirmed in 2015 through a comprehensive analysis of morphological, ecological, and mitochondrial DNA (mtDNA) traits of all putative tiger subspecies. The continental nominate subspeciesP. t. tigris constitutes two clades: a northern clade composed of the Siberian and Caspian tiger populations, and a southern clade composed of all other mainland populations.[10]
In 2017, the Cat Classification Task Force of the IUCN Cat Specialist Group revised felid taxonomy in accordance with the 2015 two-subspecies proposal and recognised only P. t. tigris and P. t. sondaica.[12] Results of a 2018 whole-genome sequencing study of 32 samples from the six living putative subspecies—the Bengal, Malayan, Indochinese, South China, Siberian and Sumatran tiger—found them to be distinct and separate clades.[13] These results were corroborated in 2021 and 2023.[14][15] The Cat Specialist Group states that "Given the varied interpretations of data, the [subspecific] taxonomy of this species is currently under review by the IUCN SSC Cat Specialist Group."[16]
The following tables are based on the classification of the tiger as of 2005,[9] and also reflect the classification recognised by the Cat Classification Task Force in 2017.[12]
This population inhabits the Indian subcontinent.[17] The Bengal tiger has shorter fur than tigers further north,[8] with a light tawny to orange-red colouration,[8][18] and relatively long and narrow nostrils.[19]
This population occurred from Turkey to around the Caspian Sea.[17] It had bright rusty-red fur with thin and closely spaced brownish stripes,[21] and a broad occipital bone.[11] Genetic analysis revealed that it was closely related to the Siberian tiger.[22] It has been extinct since the 1970s.[23]
This population lives in the Russian Far East, Northeast China and possibly North Korea.[17] The Siberian tiger has long hair and dense fur.[24] Its ground colour varies widely from ochre-yellow in winter to more reddish and vibrant after moulting.[25] The skull is shorter and broader than the skulls of tigers further south.[19]
This tiger historically lived in south-central China.[17] The skulls of the five type specimens had shorter carnassials and molars than tigers from India, a smaller cranium, orbits set closer together and larger postorbital processes; skins were yellowish with rhombus-like stripes.[26] It has a unique mtDNA haplotype due to interbreeding with ancient tiger lineages.[12][27][28] It is extinct in the wild as there has not been a confirmed sighting since the 1970s,[1] and survives only in captivity.[15]
This tiger population occurs on the Indochinese Peninsula.[17] Indochinese tiger specimens are smaller with smaller skulls than specimens from India and appear to have darker fur with slightly narrower stripes.[29][30]
The Malayan tiger was proposed as a distinct subspecies on the basis of mtDNA and micro-satellite sequences that differ from the Indochinese tiger.[31] It does not differ significantly in fur colour or skull size from Indochinese tigers.[30] There is no clear geographical barrier between tiger populations in northern Malaysia and southern Thailand.[1]
This tiger was described based on an unspecified number of skins with short and smooth hair.[24] Tigers from Java were small compared to tigers of the Asian mainland, had relatively elongated skulls compared to the Sumatran tiger, and longer, thinner and more numerous stripes.[30] The Javan tiger is thought to have gone extinct by the 1980s.[23]
This tiger occurred on Bali and had brighter fur and a smaller skull than the Javan tiger.[32][33] A typical feature of Bali tiger skulls is the narrow occipital bone, which is similar to the Javan tiger's skull.[34] The tiger went extinct in the 1940s.[23]
The type specimen from Sumatra had dark fur.[35] The Sumatran tiger has particularly long hair around the face,[17] thick body stripes,[30] and a broader and smaller nasal bone than other island tigers.[30][19]
The tiger shares the genus Panthera with the lion, leopard, jaguar and snow leopard. Results of genetic analyses indicate that the tiger and snow leopard are sister species whose lineages split from each other between 2.70 and 3.70 million years ago.[37] The tiger's whole genome sequencing shows repeated sequences that parallel those in other cat genomes.[38]
The fossil species Panthera palaeosinensis of early Pleistocene northern China was described as a possible tiger ancestor when it was discovered in 1924, but modern cladistics places it as basal to modern Panthera.[39][40]Panthera zdanskyi, which lived around the same time and place, was suggested to be a sister species of the modern tiger when it was examined in 2014.[40] However, as of 2023, at least two subsequent studies considered P. zdanskyi likely to be a synonym of P. palaeosinensis, noting that its proposed differences from that species fell within the range of individual variation.[41][42] The earliest appearance of the modern tiger species in the fossil record are jaw fragments from Lantion in China that are dated to the early Pleistocene.[40]
Middle- to late-Pleistocene tiger fossils have been found throughout China, Sumatra and Java. Prehistoric subspecies include Panthera tigris trinilensis and P. t. soloensis of Java and Sumatra, and P. t. acutidens of China; late Pleistocene and early Holocene fossils of tigers have also been found in

Detroit's diverse culture has had both local and international influence, particularly in music, with the city giving rise to the genres of Motown and techno and playing an important role in the development of jazz, hip-hop, rock, and punk. The rapid growth of Detroit in its boom years resulted in a globally unique stock of architectural monuments and historic places. Since the 2000s, conservation efforts have managed to save many architectural pieces and achieve several large-scale revitalizations, including the restoration of several historic theaters and entertainment venues, high-rise renovations, new sports stadiums, and a riverfront revitalization project.
Detroit and adjacent Windsor, Ontario, Canada separated by the Detroit River
Detroit is named after the Detroit River, connecting Lake Huron with Lake Erie. The name comes from the French word détroit meaning 'strait' as the city was situated on a narrow passage of water linking the two lakes. The river was known as le détroit du Lac Érié in French, which means 'the strait of Lake Erie'.[19][20] In the historical context, the strait included the St. Clair River, Lake St. Clair, and the Detroit River.[21][22]
Paleo-Indians inhabited areas near Detroit as early as 11,000 years ago including the culture referred to as the Mound Builders.[23] By the 17th century, the region was inhabited by Huron, Odawa, Potawatomi, and Iroquois peoples.[24] The area is known by the Anishinaabe people as Waawiiyaataanong, translating to 'where the water curves around'.[25]
The first Europeans did not penetrate into the region and reach the straits of Detroit until French missionaries and traders worked their way around the Iroquois League, with whom they were at war in the 1630s.[26] The Huron and Neutral people held the north side of Lake Erie until the 1650s, when the Iroquois pushed them and the Erie people away from the lake and its beaver-rich feeder streams in the Beaver Wars of 1649–1655.[26] By the 1670s, the war-weakened Iroquois laid claim to as far south as the

The word planet comes from the Greek πλανήται (planḗtai) 'wanderers'. In antiquity, this word referred to the Sun, Moon, and five points of light visible to the naked eye that moved across the background of the stars—namely, Mercury, Venus, Mars, Jupiter, and Saturn. Planets have historically had religious associations: multiple cultures identified celestial bodies with gods, and these connections with mythology and folklore persist in the schemes for naming newly discovered Solar System bodies. Earth itself was recognized as a planet when heliocentrism supplanted geocentrism during the 16th and 17th centuries.
With the development of the telescope, the meaning of planet broadened to include objects only visible with assistance: the moons of the planets beyond Earth; the ice giants Uranus and Neptune; Ceres and other bodies later recognized to be part of the asteroid belt; and Pluto, later found to be the largest member of the collection of icy bodies known as the Kuiper belt. The discovery of other large objects in the Kuiper belt, particularly Eris, spurred debate about how exactly to define a planet. In 2006, the International Astronomical Union (IAU) adopted a definition of a planet in the Solar System, placing the four terrestrial planets and the four giant planets in the planet category; Ceres, Pluto, and Eris are in the category of dwarf planet.[2][3][4] Many planetary scientists have nonetheless continued to apply the term planet more broadly, including dwarf planets as well as rounded satellites like the Moon.[5]
Further advances in astronomy led to the discovery of over five thousand planets outside the Solar System, termed exoplanets. These often show unusual features that the Solar System planets do not show, such as hot Jupiters—giant planets that orbit close to their parent stars, like 51 Pegasi b—and extremely eccentric orbits, such as HD 20782 b. The discovery of brown dwarfs and planets larger than Jupiter also spurred debate on the definition, regarding where exactly to draw the line between a planet and a star. Multiple exoplanets have been found to orbit in the habitable zones of their stars (where liquid water can potentially exist on a planetary surface), but Earth remains the only planet known to support life.
It is not known with certainty how planets are formed. The prevailing theory is that they coalesce during the collapse of a nebula into a thin disk of gas and dust. A protostar forms at the core, surrounded by a rotating protoplanetary disk. Through accretion (a process of sticky collision) dust particles in the disk steadily accumulate mass to form ever-larger bodies. Local concentrations of mass known as planetesimals form, and these accelerate the accretion process by drawing in additional material by their gravitational attraction. These concentrations become ever denser until they collapse inward under gravity to form protoplanets.[6] After a planet reaches a mass somewhat larger than Mars's mass, it begins to accumulate an extended atmosphere,[7] greatly increasing the capture rate of the planetesimals by means of atmospheric drag.[8][9] Depending on the accretion history of solids and gas, a giant planet, an ice giant, or a terrestrial planet may result.[10][11][12] It is thought that the regular satellites of Jupiter, Saturn, and Uranus formed in a similar way;[13][14] however, Triton was likely captured by Neptune,[15] and Earth's Moon[16] and Pluto's Charon might have formed in collisions.[17]
When the protostar has grown such that it ignites to form a star, the surviving disk is removed from the inside outward by photoevaporation, the solar wind, Poynting–Robertson drag and other effects.[18][19] Thereafter there still may be many protoplanets orbiting the star or each other, but over time many will collide, either to form a larger, combined protoplanet or release material for other protoplanets to absorb.[20] Those objects that have become massive enough will capture most matter in their orbital neighbourhoods to become planets. Protoplanets that have avoided collisions may become natural satellites of planets through a process of gravitational capture, or remain in belts of other objects to become either dwarf planets or small bodies.[21][22]
The energetic impacts of the smaller planetesimals (as well as radioactive decay) will heat up the growing planet, causing it to at least partially melt. The interior of the planet begins to differentiate by density, with higher density materials sinking toward the core.[23] Smaller terrestrial planets lose most of their atmospheres because of this accretion, but the lost gases can be replaced by outgassing from the mantle and from the subsequent impact of comets[24] (smaller planets will lose any atmosphere they gain through various escape mechanisms[25]).
With the discovery and observation of planetary systems around stars other than the Sun, it is becoming possible to elaborate, revise or even replace this account. The level of metallicity—an astronomical term describing the abundance of chemical elements with an atomic number greater than 2 (helium)—appears to determine the likelihood that a star will have planets.[26][27] Hence, a metal-rich population I star is more likely to have a substantial planetary system than a metal-poor, population II star.[28]
According to the IAU definition, there are eight planets in the Solar System, which are (in increasing distance from the Sun):[2] Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Jupiter is the largest, at 318 Earth masses, whereas Mercury is the smallest, at 0.055 Earth masses.[29]
The planets of the Solar System can be divided into categories based on their composition. Terrestrials are similar to Earth, with bodies largely composed of rock and metal: Mercury, Venus, Earth, and Mars. Earth is the largest terrestrial planet.[30]Giant planets are significantly more massive than the terrestrials: Jupiter, Saturn, Uranus, and Neptune.[30] They differ from the terrestrial planets in composition. The gas giants, Jupiter and Saturn, are primarily composed of hydrogen and helium and are the most massive planets in the Solar System. Saturn is one third as massive as Jupiter, at 95 Earth masses.[31] The ice giants, Uranus and Neptune, are primarily composed of low-boiling-point materials such as water, methane, and ammonia, with thick atmospheres of hydrogen and helium. They have a significantly lower mass than the gas giants (only 14 and 17 Earth masses).[31]
The Sun's, planets', dwarf planets' and moons' size to scale, labelled. Distance of objects is not to scale. The asteroid belt lies between the orbits of Mars and Jupiter, the Kuiper belt lies beyond Neptune's orbit.
Dwarf planets are gravitationally rounded, but have not cleared their orbits of other bodies. In increasing order of average distance from the Sun, the ones generally agreed among astronomers are Ceres, Orcus, Pluto, Haumea, Quaoar, Makemake, Gonggong, Eris, and Sedna.[32][33] Ceres is the largest object in the asteroid belt, located between the orbits of Mars and Jupiter. The other eight all orbit beyond Neptune. Orcus, Pluto, Haumea, Quaoar, and Makemake orbit in the Kuiper belt, which is a second belt of small Solar System bodies beyond the orbit of Neptune. Gonggong and Eris orbit in the scattered disc, which is somewhat further out and, unlike the Kuiper belt, is unstable towards interactions with Neptune. Sedna is the largest known detached object, a population that never comes close enough to the Sun to interact with any of the classical planets; the origins of their orbits are still being debated. All nine are similar to terrestrial planets in having a solid surface, but they are made of ice and rock rather than rock and metal. Moreover, all of them are smaller than Mercury, with Pluto being the largest known dwarf planet and Eris being the most massive.[34][35]
There are at least nineteen planetary-mass moons or satellite planets—moons large enough to take on ellipsoidal shapes:[4]
The Moon, Io, and Europa have compositions similar to the terrestrial planets; the others are made of ice and rock like the dwarf planets, with Tethys being made of almost pure ice. Europa is often considered an icy planet, though, because its surface ice layer makes it difficult to study its interior.[4][36] Ganymede and Titan are larger than Mercury by radius, and Callisto almost equals it, but all three are much less massive. Mimas is the smallest object generally agreed to be a geophysical planet, at about six millionths of Earth's mass, though there are many larger bodies that may not be geophysical planets (e.g. Salacia).[32]
In early 1992, radio astronomers Aleksander Wolszczan and Dale Frail announced the discovery of two planets orbiting the pulsarPSR 1257+12.[40] This discovery was confirmed and is generally considered to be the first definitive detection of exoplanets. Researchers suspect they formed from a disk remnant left over from the supernova that produced the pulsar.[41]
In 2011, the Kepler Space Telescope team reported the discovery of the first Earth-sized exoplanets orbiting a Sun-like star, Kepler-20e and Kepler-20f.[45][46][47] Since that time, more than 100 planets have been identified that are approximately the same size as Earth, 20 of which orbit in the habitable zone of their star—the range of orbits where a terrestrial planet could sustain liquid water on its surface, given enough atmospheric pressure.[48][49][50] One in five Sun-like stars is thought to have an Earth-sized planet in its habitable zone, which suggests that the nearest would be expected to be within 12 light-years distance from Earth.[a] The frequency of occurrence of such terrestrial planets is one of the variables in the Drake equation, which estimates the number of intelligent, communicating civilizations that exist in the Milky Way.[53]
There are types of planets that do not exist in the Solar System: super-Earths and mini-Neptunes, which have masses between that of Earth and Neptune. Objects less than about twice the mass of Earth are expected to be rocky like Earth; beyond that, they become a mixture of volatiles and gas like Neptune.[54] The planet Gliese 581c, with a mass 5.5–10.4 times the mass of Earth,[55] attracted attention upon its discovery for potentially being in the habitable zone,[56] though later studies concluded that it is actually too close to its star to be habitable.[57] Planets more massive than Jupiter are also known, extending seamlessly into the realm of brown dwarfs.[58]
Exoplanets have been found that are much closer to their parent star than any planet in the Solar System is to the Sun. Mercury, the closest planet to the Sun at 0.4 AU, takes 88 days for an orbit, but ultra-short period planets can orbit in less than a day. The Kepler-11 system has five of its planets in shorter orbits than Mercury's, all of them much more massive than Mercury. There are hot Jupiters, such as 51 Pegasi b,[42] that orbit very close to their star and may evaporate to become chthonian planets, which are the leftover cores. There are also exoplanets that are much farther from their star. Neptune is 30 AU from the Sun and takes 165 years to orbit, but there are exoplanets that are thousands of AU from their star and take more than a million years to orbit (e.g. COCONUTS-2b).[59]
Although each planet has unique physical characteristics, a number of broad commonalities do exist among them. Some of these characteristics, such as rings or natural satellites, have only as yet been observed in planets in the Solar System, whereas others are commonly observed in exoplanets.[60]
The orbit of the planet Neptune compared to that of Pluto. Note the elongation of Pluto's orbit in relation to Neptune's (eccentricity), as well as its large angle to the ecliptic (inclination).
In the Solar System, all the planets orbit the Sun in the same direction as the Sun rotates: counter-clockwise as seen from above the Sun's north pole. At least one exoplanet, WASP-17b, has been found to orbit in the opposite direction to its star's rotation.[61] The period of one revolution of a planet's orbit is known as its sidereal period or year.[62] A planet's year depends on its distance from its star; the farther a planet is from its star, the longer the distance it must travel and the slower its speed, since it is less affected by its star's gravity.
No planet's orbit is perfectly circular, and hence the distance of each from the host star varies over the course of its year. The closest approach to its star is called its periastron, or perihelion in the Solar System, whereas its farthest separation from the star is called its apastron (aphelion). As a planet approaches periastron, its speed increases as it trades gravitational potential energy for kinetic energy, just as a falling object on Earth accelerates as it falls. As the planet nears apastron, its speed decreases, just as an object thrown upwards on Earth slows down as it reaches the apex of its trajectory.[63]
Each planet's orbit is delineated by a set of elements:
The eccentricity of an orbit describes the elongation of a planet's elliptical (oval) orbit. Planets with low eccentricities have more circular orbits, whereas planets with high eccentricities have more elliptical orbits. The planets and large moons in the Solar System have relatively low eccentricities, and thus nearly circular orbits.[62] The comets and many Kuiper belt objects, as well as several exoplanets, have very high eccentricities, and thus exceedingly elliptical orbits.[64][65]
The semi-major axis gives the size of the orbit. It is the distance from the midpoint to the longest diameter of its elliptical orbit. This distance is not the same as its apastron, because no planet's orbit has its star at its exact centre.[62]
The inclination of a planet tells how far above or below an established reference plane its orbit is tilted. In the Solar System, the reference plane is the plane of Earth's orbit, called the ecliptic. For exoplanets, the plane, known as the sky plane or plane of the sky, is the plane perpendicular to the observer's line of sight from Earth.[66] The orbits of the eight major planets of the Solar System all lie very close to the ecliptic; however, some smaller objects like Pallas, Pluto, and Eris orbit at far more extreme angles to it, as do comets.[67] The large moons are generally not very inclined to their parent planets' equators, but Earth's Moon, Saturn's Iapetus, and Neptune's Triton are exceptions. Triton is unique among the large moons in that it orbits retrograde, i.e. in the direction opposite to its parent planet's rotation.[68]
The points at which a planet crosses above and below its reference plane are called its ascending and descending nodes.[62] The longitude of the ascending node is the angle between the reference plane's 0 longitude and the planet's ascending node. The argument of periapsis (or perihelion in the Solar System) is the angle between a planet's ascending node and its closest approach to its star.[62]
Earth's axial tilt is about 23.4°. It oscillates between 22.1° and 24.5° on a 41,000-year cycle and is currently decreasing.
Planets have varying degrees of axial tilt; they spin at an angle to the plane of their stars' equators. This causes the amount of light received by each hemisphere to vary over the course of its year; when the northern hemisphere points away from its star, the southern hemisphere points towards it, and vice versa. Each planet therefore has seasons, resulting in changes to the climate over the course of its year. The time at which each hemisphere points farthest or nearest from its star is known as its solstice. Each planet has two in the course of its orbit; when one hemisphere has its summer solstice with its day being the longest, the other has its winter solstice when its day is shortest. The varying amount of light and heat received by each hemisphere creates annual changes in weather patterns for each half of the planet. Jupiter's axial tilt is very small, so its seasonal variation is minimal; Uranus, on the other hand, has an axial tilt so extreme it is virtually on its side, which means that its hemispheres are either continually in sunlight or continually in darkness around the time of its solstices.[69] In the Solar System, Mercury, Venus, Ceres, and Jupiter have very small tilts; Pallas, Uranus, and Pluto have extreme ones; and Earth, Mars, Vesta, Saturn, and Neptune have moderate ones.[70][71][72][73] Among exoplanets, axial tilts are not known for certain, though most hot Jupiters are believed to have a negligible axial tilt as a result of their proximity to their stars.[74] Similarly, the axial tilts of the planetary-mass moons are near zero,[75] with Earth's Moon at 6.687° as the biggest exception;[76] additionally, Callisto's axial tilt varies between 0 and about 2 degrees on timescales of thousands of years.[77]
This program unpacks Playstation 3 Theme files (.p3t) so that you can touch-up an existing theme to your likings or use a certain wallpaper from it (as many themes have multiple). But remember, if you use content from another theme and release it, be sure to give credit!
Download p3textractor.zip from above. Extract the files to a folder with a program such as WinZip or WinRAR. Now there are multiple ways to extract the theme.
The first way is to simply open the p3t file with p3textractor.exe. If you don’t know how to do this, right click the p3t file and select Open With. Alternatively, open the p3t file and it will ask you to select a program to open with. Click Browse and find p3textractor.exe from where you previously extracted it to. It will open CMD and extract the theme to extracted.[filename]. After that, all you need to do for any future p3t files is open them and it will extract.
The second way is very simple. Just drag the p3t file to p3textractor.exe. It will open CMD and extract the theme to extracted.[filename].
For the third way, first put the p3t file you want to extract into the same folder as p3textractor.exe. Open CMD and browse to the folder with p3extractor.exe. Enter the following: p3textractor filename.p3t [destination path]Replace filename with the name of the p3t file, and replace [destination path] with the name of the folder you want the files to be extracted to. A destination path is not required. By default it will extract to extracted.filename.
