Dette vil være bra for din karriere. [45] Lowell had made a prediction of Planet X's orbit and position in 1915 that was fairly close to Pluto's actual orbit and its position at that time; Ernest W. Brown concluded soon after Pluto's discovery that this was a coincidence.[46]. Computer processing of many such observations can be used to create a brightness map. [69], Researchers on both sides of the debate gathered in August 2008, at the Johns Hopkins University Applied Physics Laboratory for a conference that included back-to-back talks on the current IAU definition of a planet. In the 1840s, Urbain Le Verrier used Newtonian mechanics to predict the position of the then-undiscovered planet Neptune after analyzing perturbations in the orbit of Uranus. Sofern den falschen Menschen Geheimnisse offenbart werden, könnten diese die erhaltenen Informationen zu einem späteren Zeitpunkt gegen uns verwenden. [19] Vesto Melvin Slipher, the observatory director, gave the job of locating Planet X to 23-year-old Clyde Tombaugh, who had just arrived at the observatory after Slipher had been impressed by a sample of his astronomical drawings. Copy and Paste. Mike Brown, the astronomer who discovered Eris, said "through this whole crazy, circus-like procedure, somehow the right answer was stumbled on. [61] He also stated that because less than five percent of astronomers voted for it, the decision was not representative of the entire astronomical community. When the two longitudes are the same—that is, when one could draw a straight line through both nodes and the Sun—Pluto's perihelion lies exactly at 90°, and hence it comes closest to the Sun when it is highest above Neptune's orbit. At the equator, temperatures can drop to −240 °C (−400.0 °F; 33.1 K), causing nitrogen to freeze as water would freeze on Earth. [80], In 2012, it was hypothesized that 15810 Arawn could be a quasi-satellite of Pluto, a specific type of co-orbital configuration. It's been a long time coming. At such densities, nitrogen could flow across the surface as liquid. In order of distance from Pluto they are Styx, Nix, Kerberos, and Hydra. [135] The satellites' orbits are circular (eccentricity < 0.006) and coplanar with Pluto's equator (inclination < 1°),[136][137] and therefore tilted approximately 120° relative to Pluto's orbit. The New Horizons spacecraft, which flew by Pluto in July 2015, is the first and so far only attempt to explore Pluto directly. [149] Like other Kuiper-belt objects (KBOs), Pluto shares features with comets; for example, the solar wind is gradually blowing Pluto's surface into space. [64] The New Mexico House of Representatives passed a resolution in honor of Tombaugh, a longtime resident of that state, that declared that Pluto will always be considered a planet while in New Mexican skies and that March 13, 2007, was Pluto Planet Day. Pluto i hus Symbol & Betydninger - 2020. nyheter. As Neptune migrated outward, it approached the objects in the proto-Kuiper belt, setting one in orbit around itself (Triton), locking others into resonances, and knocking others into chaotic orbits. [82] The minimum separation between Pluto and Neptune actually occurs near the time of Pluto's aphelion. Saturn Astrology I represent the areas in your life where you need that extra push to overcome the challenges presented. Nix and Hydra were both discovered in 2005,[133] Kerberos was discovered in 2011,[134] and Styx was discovered in 2012. It is the largest known trans-Neptunian object by volume but is less massive than Eris. [104][105] It has no craters that were visible to New Horizons, indicating that its surface is less than 10 million years old. Andre kan prøve å krangle med deg om ideene dine. Forsøk å holde forholdene jevn. This is a consequence of the Kozai mechanism,[80] which relates the eccentricity of an orbit to its inclination to a larger perturbing body—in this case Neptune. Pluto has been in Capricorn since January 24th, 2008, and will continue to roam in the earthy pragmatic sign until 2024 (note: it will exit Capricorn in 2023 but retrograde for some time). [22] Lowell Observatory, which had the right to name the new object, received more than 1,000 suggestions from all over the world, ranging from Atlas to Zymal. When Pluto is closest to the Sun, and hence closest to Neptune's orbit as viewed from above, it is also the farthest above Neptune's path. This moves Pluto into a slightly larger orbit, where it travels slightly more slowly, according to Kepler's third law. These masses would cause the body to reorient itself, leading to its unusual axial tilt of 120°. [165] The images, taken from a distance of approximately 4.2 billion kilometers, confirmed the spacecraft's ability to track distant targets, critical for maneuvering toward Pluto and other Kuiper belt objects. Pluto is now known to be the largest member of the Kuiper belt,[j] a stable belt of objects located between 30 and 50 AU from the Sun. Prøv imidlertid å bryte ut av sjenanse. [25] She suggested it in a conversation with her grandfather Falconer Madan, a former librarian at the University of Oxford's Bodleian Library, who passed the name to astronomy professor Herbert Hall Turner, who cabled it to colleagues in the United States. It was the first and the largest Kuiper belt object to be discovered. Pluto i astrologiske hus . Beginning in the 1990s, its status as a planet was questioned following the discovery of several objects of similar size in the Kuiper belt, including the dwarf planet Eris. Rather, it is considered a member of a linked population called the scattered disc. [157] A computer model created in 2004 by Alessandro Morbidelli of the Observatoire de la Côte d'Azur in Nice suggested that the migration of Neptune into the Kuiper belt may have been triggered by the formation of a 1:2 resonance between Jupiter and Saturn, which created a gravitational push that propelled both Uranus and Neptune into higher orbits and caused them to switch places, ultimately doubling Neptune's distance from the Sun. [170] They include mapping the surface at 9.1 m (30 ft) per pixel, observations of Pluto's smaller satellites, observations of how Pluto changes as it rotates on its axis, and topographic mapping of Pluto's regions that are covered in long-term darkness due to its axial tilt. Numerical studies have shown that over millions of years, the general nature of the alignment between the orbits of Pluto and Neptune does not change. The pre–New Horizons estimate for the diameter of the core 1700 km, 70% of Pluto's diameter. [161] It looks star-like and without a visible disk even in large telescopes, because its angular diameter is only 0.11". Symbols include the chemical elements, three primes, and philosopher's stone. Unknown to Lowell, his surveys had captured two faint images of Pluto on March 19 and April 7, 1915, but they were not recognized for what they were. [2]), In 1978, the discovery of Pluto's moon Charon allowed the measurement of Pluto's mass for the first time: roughly 0.2% that of Earth, and far too small to account for the discrepancies in the orbit of Uranus. Pluto ist verbunden mit den regenerativen Kräften in uns. [150] It has been claimed that if Pluto were placed as near to the Sun as Earth, it would develop a tail, as comets do. Fordi Pluto er så langt borte, har den ikke så stor innvirkning på livet ditt som en nærmere eller store planeter gjør. The equatorial region of the sub-Charon hemisphere of Pluto has only been imaged at low resolution, as New Horizons made its closest approach to the anti-Charon hemisphere. Jupiter symbol meanings are closely aligned with manifestation because of its situation in the solar system. The two orbits do not intersect. [137][140], The Pluto–Charon system is one of the few in the Solar System whose barycenter lies outside the primary body; the Patroclus–Menoetius system is a smaller example, and the Sun–Jupiter system is the only larger one. [90], In 2007, observations by the Gemini Observatory of patches of ammonia hydrates and water crystals on the surface of Charon suggested the presence of active cryo-geysers. On July 29, 2005, astronomers at Caltech announced the discovery of a new trans-Neptunian object, Eris, which was substantially more massive than Pluto and the most massive object discovered in the Solar System since Triton in 1846. Symbole Homme Je dois aller chercher les garçons, ou bien ich gehe mal für kleine Königstiger. Du vil bli flink til å finne og løse problemer som andre kanskje ikke legger merke til. This is called polar wander. [91] The reason for this unusual orientation has been debated. [19], Tombaugh's task was to systematically image the night sky in pairs of photographs, then examine each pair and determine whether any objects had shifted position. Dette kan også forårsake problemer på jobben. [53][51] The IAU further decided that bodies that, like Pluto, meet criteria 1 and 2, but do not meet criterion 3 would be called dwarf planets. Aus diesem Grund sollte beim rückläufigen Pluto darauf geachtet werden, wem das Vertrauen geschenkt wird. The scientific goals of New Horizons were to characterize the global geology and morphology of Pluto and its moon Charon, map their surface composition, and analyze Pluto's neutral atmosphere and its escape rate. Pluto i det ellevte huset er litt forvirrende. [15] Estimates of Pluto's mass were revised downward throughout the 20th century. Science is self-correcting eventually, even when strong emotions are involved. [73][74][75], Pluto's orbital period is currently about 248 years. Even if Pluto's orbit were not inclined, the two bodies could never collide. Pluto er også et transneptunsk objekt. KBOs with this orbital resonance are called "plutinos", after Pluto. They refer to the standard equinox J2000, the barycenter of the Solar System, and the epoch J2000. The darker sections of both orbits show where they pass below the, Distribution of over 1000 craters of all ages in the northern anti-Charon quadrant of Pluto. This article is about the dwarf planet. The Pluto–Charon barycenter came to perihelion on September 5, 1989,[3][i] and was last closer to the Sun than Neptune between February 7, 1979, and February 11, 1999. Alexander Mills Legg igjen en kommentar. [7] Because the decay of radioactive elements would eventually heat the ices enough for the rock to separate from them, scientists expect that Pluto's internal structure is differentiated, with the rocky material having settled into a dense core surrounded by a mantle of water ice. First, Pluto's argument of perihelion, the angle between the point where it crosses the ecliptic and the point where it is closest to the Sun, librates around 90°. [99] Pluto's color is more similar to that of Io with slightly more orange and significantly less red than Mars. The Plutonian system is highly compact: the five known satellites orbit within the inner 3% of the region where prograde orbits would be stable. Du vil imidlertid fortsatt holde deler av livet ditt privat. Light from the Sun takes 5.5 hours to reach Pluto at its average distance (39.5 AU). "[7], In Western parts of Sputnik Planitia there are fields of transverse dunes formed by the winds blowing from the center of Sputnik Planitia in the direction of surrounding mountains. This mosaic strip – extending across the hemisphere that faced the New Horizons spacecraft as it flew past Pluto. [16][17] There are fourteen other known precovery observations, with the earliest made by the Yerkes Observatory on August 20, 1909. [15] By 1909, Lowell and William H. Pickering had suggested several possible celestial coordinates for such a planet. Pluto's astronomical symbol (, Unicode U+2647, ♇) was then created as a monogram constructed from the letters "PL". Forsøk å holde tillitsnivået høyt i løpet av denne tiden. Its surface gravity is 0.063 g (compared to 1 g for Earth and 0.17 g for the Moon). After Pluto was discovered in 1930 it was declared to be the ninth planet from the Sun. [97] Pluto is one of the most contrastive bodies in the Solar System, with as much contrast as Saturn's moon Iapetus. Ebenso sollte darauf geachtet werden, das erhaltenes Vertrauen anderer … Du vil sannsynligvis være skeptisk til hva du hører eller leser når Pluto er i det tredje huset. In 1906, Percival Lowell—a wealthy Bostonian who had founded Lowell Observatory in Flagstaff, Arizona, in 1894—started an extensive project in search of a possible ninth planet, which he termed "Planet X". Dette er imidlertid ikke en god holdning å ta på jobb eller på skolen. [117] In March 2014, Lellouch, de Bergh et al. Copy and paste this emoji: Copy This Unicode character has no emoji version, meaning this is intended to display only as a black and white glyph on most platforms. The dune wavelengths are in the range of 0.4–1 km and they are likely consists of methane particles 200–300 μm in size. Observations were made of the change in the total average brightness of the Pluto–Charon system during the eclipses. [31], Most languages use the name "Pluto" in various transliterations. [152] It has been proposed that Pluto may have formed as a result of the agglomeration of numerous comets and Kuiper-belt objects.[153][154]. Images from the Hubble Space Telescope in 1996 cover 85% of Pluto and show large albedo features down to about 75° South. [79], The 2:3 resonance between the two bodies is highly stable and has been preserved over millions of years. New Horizons principal investigator Alan Stern has advocated for a Cassini-style orbiter that would launch around 2030 (the 100th anniversary of Pluto's discovery) and use Charon's gravity to adjust its orbit as needed to fulfill science objectives after arriving at the Pluto system. In February 2000 the Hayden Planetarium in New York City displayed a Solar System model of only eight planets, which made headlines almost a year later. It is less massive than the dwarf planet Eris, a trans-Neptunian object discovered in 2005, though Pluto has a larger diameter of 2376.6 km[5] compared to Eris's approximate diameter of 2326 km. Endringen vil komme inn i livet ditt; prøv å forberede deg på dette. [92] According to a paper released from the University of Arizona, this could be caused by masses of frozen nitrogen building up in shadowed areas of the dwarf planet. [2][90] Like Uranus, Pluto rotates on its "side" in its orbital plane, with an axial tilt of 120°, and so its seasonal variation is extreme; at its solstices, one-fourth of its surface is in continuous daylight, whereas another fourth is in continuous darkness. U+1F6B9 Toilettes pour dames Les toilettes pour dames sont souvent représentées vec un schéma de personnage féminin. [130], Pluto has five known natural satellites. In September 2006, the IAU included Pluto, and Eris and its moon Dysnomia, in their Minor Planet Catalogue, giving them the official minor planet designations "(134340) Pluto", "(136199) Eris", and "(136199) Eris I Dysnomia". Each cycle lasts about 495 years. [23] Tombaugh urged Slipher to suggest a name for the new object quickly before someone else did. Når Pluto er i det 6. huset i fødselsskjemaet ditt, vil du sannsynligvis lykkes med jobb eller skole. With the new figures added in, the discrepancies, and with them the need for a Planet X, vanished. The final choice of name was helped in part by the fact that the first two letters of Pluto are the initials of Percival Lowell.

This "view from above" shows how Pluto's orbit (in red) is less circular than Neptune's (in blue), and how Pluto is sometimes closer to the Sun than Neptune. This is enough to show the extent of the temperate-zone maculae. More specifically, its own gravity should pull it into a shape defined by, This page was last edited on 15 November 2020, at 16:27. Pluto, the planet, dwarf planet, or trans-Neptunian Kuiper belt object, has had an interesting life since it first came to prominence in 1930, after its discovery by Clyde Tombaugh. The resolution asserted that Pluto was "unfairly downgraded to a 'dwarf' planet" by the IAU. ", "My response to 2006 IAU Resolutions 5a and 6a", "A joint memorial. [137][139] When precession is accounted for, the orbital periods of Styx, Nix, and Hydra are in an exact 18:22:33 ratio. [95] The mountains are made of water ice. The mean elements here are from the Theory of the Outer Planets (TOP2013) solution by the Institut de mécanique céleste et de calcul des éphémérides (IMCCE). [30] In 1941, Glenn T. Seaborg named the newly created element plutonium after Pluto, in keeping with the tradition of naming elements after newly discovered planets, following uranium, which was named after Uranus, and neptunium, which was named after Neptune. [21], The discovery made headlines around the globe. The resultant expulsion of objects from the proto-Kuiper belt could also explain the Late Heavy Bombardment 600 million years after the Solar System's formation and the origin of the Jupiter trojans. [164] These remained the most detailed maps of Pluto until the flyby of New Horizons in July 2015, because the two cameras on the HST used for these maps were no longer in service.[164]. [151] This claim has been disputed with the argument that Pluto's escape velocity is too high for this to happen. Pluto received a unanimous vote. [106] Latest studies have shown that the surface has an age of 180000+90000−40000 years. The semi-major axis and period are presently getting longer.[79]. [141] The similarity in size of Charon and Pluto has prompted some astronomers to call it a double dwarf planet. Pluto ble tidligere regnet som den niende og ytterste av planetene i solsystemet, men har siden 2006 blitt regnet som en dvergplanet. [40] (Pluto's albedo is 1.4–1.9 times that of Earth.

[83] This prevents their orbits from changing relative to one another, and so the two bodies can never pass near each other. If Pluto's period is slightly shorter than 3/2 of Neptune, its orbit relative to Neptune will drift, causing it to make closer approaches behind Neptune's orbit. Declaring Pluto a planet and declaring March 13, 2007, 'Pluto planet day' at the legislature", "Illinois General Assembly: Bill Status of SR0046, 96th General Assembly", "Is Rekindling the Pluto Planet Debate a Good Idea? [33], Once Pluto was found, its faintness and lack of a resolvable disc cast doubt on the idea that it was Lowell's Planet X. Pluto i hus liker å kontrollere skapelse så vel som ødeleggelse. [137] There is a sequence of approximate ratios, 3:4:5:6, between the periods of Styx, Nix, Kerberos, and Hydra with that of Charon; the ratios become closer to being exact the further out the moons are. [125], Determinations of Pluto's size had been complicated by its atmosphere,[119] and hydrocarbon haze.
