Pluto ist der größte und zweitmassivste bekannte Zwergplanet und das am längsten bekannte Objekt des Kuipergürtels. Er besitzt etwa ein Drittel des Volumens. Zum Startzeitpunkt galt Pluto noch als vollwertiger Planet und war als einziger Planet noch von keiner Raumsonde erforscht worden. Wenige Monate nach dem​. Am Februar feiert Pluto das Jubiläum seiner Entdeckung durch Clyde Tombaugh. Mehr als 70 Jahre lang galt er als neunter Planet unseres. Zwergplanet Pluto. Pluto, früher der äußerste Planet des Sonnensystems, ist eine echte Herausforderung für Sterngucker. Denn Pluto ist nicht nur sehr weit weg. Die erste Sonde, die Pluto wirklich nahe kam, war New Horizons: flog sie mit nur Kilometern Abstand an dem fernen Zwergplaneten vorbei und.

Er war einmal der äußerste Planet des Sonnensystems: Pluto. Doch dann wurde Pluto zum Zwergplaneten degradiert. Dabei hat er sogar. Planet: Nur knapp größer als Pluto. Amerikanische Astronomen haben mit dem Weltraumteleskop Hubble den Durchmesser des " Planeten" UB Die sehr lange Frage lautete: „Mehr als 70 Jahre lang galt Pluto als neunter Planet unseres Sonnensystems – bis ihm die Internationale.

In the picture above, the arrows show the direction the planets and Pluto rotate. Notice Pluto's spin goes the opposite direction of all the others except Venus and Uranus.

In the picture above, the arrows show which direction the planets' and Pluto's axes of rotation point. Notice Pluto's and Uranus' point along the same plane as their orbits , instead of more or less "up and down.

Like the planets, Pluto's spin axis stays pointed in the same direction as it orbits the sun. But unlike all planets except Uranus, Pluto is tipped on its side.

The planets' axes of rotation stand more or less upright from the plane of their orbits. If you lived on Pluto, you'd have to live Earth years to celebrate your first birthday in Pluto-years.

If you lived on Pluto, you would see Charon from only one side of the planet. Charon's orbit around Pluto takes about six and one-half Earth days.

Pluto's day that is, one complete rotation takes exactly the same amount of time. So, Charon always "hovers" over the same spot on Pluto's surface, and the same side of Charon always faces Pluto.

At Pluto's current distance from the sun, the temperature on its surface is about degrees below zero Fahrenheit! It will get even colder as it moves farther from the sun.

From Pluto, the sun looks like just a bright dot in the sky, the brightest star visible. The light from the sun is as bright on Pluto as the light from the full Moon is on Earth.

If you weigh pounds on Earth, you would weigh only 7 pounds on Pluto! Pluto orbits in a far-out region of the solar system called the Kuiper rhymes with viper Belt.

There are lots of icy, rocky objects out there. But they are so far from the sun they are really hard to see, even with powerful telescopes.

Let's Go There! We finally got to visit Pluto, Charon, and the Kuiper Belt! This mission is called New Horizons.

The spacecraft arrived at Pluto in July , and will continue to study other objects in the Kuiper Belt from about to With New Horizons , we are visiting and learning about the objects at the very edge of our solar system.

They may help us understand how our solar system formed. But not any more. Brown concluded soon after Pluto's discovery that this was a coincidence.

There are two primary definitions of 'planet'. Disregarding the often inconsistent technical details, they are whether a body acts like a planet e.

Pluto meets the second definition but not the first. From onward, many bodies were discovered orbiting in the same volume as Pluto, showing that Pluto is part of a population of objects called the Kuiper belt.

This made its official status as a planet controversial, with many questioning whether Pluto should be considered together with or separately from its surrounding population.

Museum and planetarium directors occasionally created controversy by omitting Pluto from planetary models of the Solar System.

In February the Hayden Planetarium in New York City displayed a Solar System model of only eight planets, which made headlines almost a year later.

Ceres , Pallas , Juno and Vesta lost their planet status after the discovery of many other asteroids. Similarly, objects increasingly closer in size to Pluto were discovered in the Kuiper belt region.

On July 29, , 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 Its discoverers and the press initially called it the tenth planet , although there was no official consensus at the time on whether to call it a planet.

The debate came to a head in August , with an IAU resolution that created an official definition for the term "planet".

According to this resolution, there are three conditions for an object in the Solar System to be considered a planet:.

Pluto fails to meet the third condition. There has been some resistance within the astronomical community toward the reclassification. Buie , then at the Lowell Observatory, petitioned against the definition.

Mike Brown , the astronomer who discovered Eris, said "through this whole crazy, circus-like procedure, somehow the right answer was stumbled on.

It's been a long time coming. Science is self-correcting eventually, even when strong emotions are involved.

Public reception to the IAU decision was mixed. The resolution asserted that Pluto was "unfairly downgraded to a 'dwarf' planet" by the IAU.

In , in its 17th annual words-of-the-year vote, the American Dialect Society voted plutoed as the word of the year.

To "pluto" is to "demote or devalue someone or something". Researchers on both sides of the debate gathered in August , 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.

Pluto's orbital period is currently about years. Its orbital characteristics are substantially different from those of the planets, which follow nearly circular orbits around the Sun close to a flat reference plane called the ecliptic.

This eccentricity means a small region of Pluto's orbit lies closer to the Sun than Neptune's. The Pluto—Charon barycenter came to perihelion on September 5, , [3] [i] and was last closer to the Sun than Neptune between February 7, , and February 11, In the long term, Pluto's orbit is chaotic.

The semi-major axis of Pluto's orbit varies between about The semi-major axis and period are presently getting longer. Despite Pluto's orbit appearing to cross that of Neptune when viewed from directly above, the two objects' orbits are aligned so that they can never collide or even approach closely.

The two orbits do not intersect. 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.

Pluto's orbit passes about 8 AU above that of Neptune, preventing a collision. This alone is not enough to protect Pluto; perturbations from the planets especially Neptune could alter Pluto's orbit such as its orbital precession over millions of years so that a collision could be possible.

However, Pluto is also protected by its orbital resonance with Neptune : for every two orbits that Pluto makes around the Sun, Neptune makes three.

Each cycle lasts about years. The resonance between the two bodies is highly stable and has been preserved over millions of years. Even if Pluto's orbit were not inclined, the two bodies could never collide.

The strong gravitational pull between the two causes angular momentum to be transferred to Pluto, at Neptune's expense.

This moves Pluto into a slightly larger orbit, where it travels slightly more slowly, according to Kepler's third law. After many such repetitions, Pluto is sufficiently slowed, and Neptune sufficiently sped up, that Pluto's orbit relative to Neptune drifts in the opposite direction until the process is reversed.

The whole process takes about 20, years to complete. 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.

These arise principally from two additional mechanisms besides the mean-motion resonance. 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.

The closest such angular separation occurs every 10, years. Second, the longitudes of ascending nodes of the two bodies—the points where they cross the ecliptic—are in near-resonance with the above libration.

This is known as the superresonance. All the Jovian planets , particularly Jupiter, play a role in the creation of the superresonance.

In , it was hypothesized that Arawn could be a quasi-satellite of Pluto, a specific type of co-orbital configuration. Pluto's rotation period , its day, is equal to 6.

Research from the University of Arizona has suggested that it may be due to the way that a body's spin will always adjust to minimise energy.

This could mean a body reorienting itself to put extraneous mass near the equator and regions lacking mass tend towards the poles.

This is called polar wander. The buildup of nitrogen is due to Pluto's vast distance from the Sun. The same effect seen on Pluto would be observed on Earth were the Antarctic ice sheet several times larger.

The plains on Pluto's surface are composed of more than 98 percent nitrogen ice , with traces of methane and carbon monoxide. 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.

The dune wavelengths are in the range of 0. Pluto's density is 1. Pluto's diameter is 2 Its surface gravity is 0. The discovery of Pluto's satellite Charon in enabled a determination of the mass of the Pluto—Charon system by application of Newton's formulation of Kepler's third law.

Observations of Pluto in occultation with Charon allowed scientists to establish Pluto's diameter more accurately, whereas the invention of adaptive optics allowed them to determine its shape more accurately.

With less than 0. The mass is much less than thought before Charon was discovered. Pluto is more than twice the diameter and a dozen times the mass of Ceres , the largest object in the asteroid belt.

It is less massive than the dwarf planet Eris , a trans-Neptunian object discovered in , though Pluto has a larger diameter of Determinations of Pluto's size had been complicated by its atmosphere, [] and hydrocarbon haze.

Pluto has a tenuous atmosphere consisting of nitrogen N 2 , methane CH 4 , and carbon monoxide CO , which are in equilibrium with their ices on Pluto's surface.

It was initially thought that, as Pluto moves away from the Sun, its atmosphere should gradually freeze onto the surface; studies of New Horizons data and ground-based occultations show that Pluto's atmospheric density increases, and that it likely remains gaseous throughout Pluto's orbit.

At such densities, nitrogen could flow across the surface as liquid. Pluto has five known natural satellites. The closest to Pluto is Charon.

First identified in by astronomer James Christy , Charon is the only moon of Pluto that may be in hydrostatic equilibrium ; Charon's mass is sufficient to cause the barycenter of the Pluto—Charon system to be outside Pluto.

Beyond Charon there are four much smaller circumbinary moons. Nix and Hydra were both discovered in , [] Kerberos was discovered in , [] and Styx was discovered in The orbital periods of all Pluto's moons are linked in a system of orbital resonances and near resonances.

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.

From any position on either body, the other is always at the same position in the sky, or always obscured. In , 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.

Pluto's moons are hypothesized to have been formed by a collision between Pluto and a similar-sized body, early in the history of the Solar System.

The collision released material that consolidated into the moons around Pluto. Pluto's origin and identity had long puzzled astronomers.

One early hypothesis was that Pluto was an escaped moon of Neptune, [] knocked out of orbit by its largest current moon, Triton.

This idea was eventually rejected after dynamical studies showed it to be impossible because Pluto never approaches Neptune in its orbit.

Pluto's true place in the Solar System began to reveal itself only in , when astronomers began to find small icy objects beyond Neptune that were similar to Pluto not only in orbit but also in size and composition.

This trans-Neptunian population is thought to be the source of many short-period comets. 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.

Though Pluto is the largest Kuiper belt object discovered, [] Neptune's moon Triton , which is slightly larger than Pluto, is similar to it both geologically and atmospherically, and is thought to be a captured Kuiper belt object.

Rather, it is considered a member of a linked population called the scattered disc. A large number of Kuiper belt objects, like Pluto, are in a orbital resonance with Neptune.

KBOs with this orbital resonance are called " plutinos ", after Pluto. Like other members of the Kuiper belt, Pluto is thought to be a residual planetesimal ; a component of the original protoplanetary disc around the Sun that failed to fully coalesce into a full-fledged planet.

Most astronomers agree that Pluto owes its current position to a sudden migration undergone by Neptune early in the Solar System's formation.

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.

The objects in the scattered disc , a dynamically unstable region overlapping the Kuiper belt, are thought to have been placed in their current positions by interactions with Neptune's migrating resonances.

Pluto's distance from Earth makes its in-depth study and exploration difficult. Pluto's visual apparent magnitude averages The earliest maps of Pluto, made in the late s, were brightness maps created from close observations of eclipses by its largest moon, Charon.

Observations were made of the change in the total average brightness of the Pluto—Charon system during the eclipses.

For example, eclipsing a bright spot on Pluto makes a bigger total brightness change than eclipsing a dark spot.

Computer processing of many such observations can be used to create a brightness map. This method can also track changes in brightness over time.

Better maps were produced from images taken by the Hubble Space Telescope HST , which offered higher resolution , and showed considerably more detail, [98] resolving variations several hundred kilometers across, including polar regions and large bright spots.

The New Horizons spacecraft, which flew by Pluto in July , is the first and so far only attempt to explore Pluto directly.

Launched in , it captured its first distant images of Pluto in late September during a test of the Long Range Reconnaissance Imager.

In early the craft made use of a gravity assist from Jupiter. New Horizons made its closest approach to Pluto on July 14, , after a 3,day journey across the Solar System.

Scientific observations of Pluto began five months before the closest approach and continued for at least a month after the encounter.

Observations were conducted using a remote sensing package that included imaging instruments and a radio science investigation tool, as well as spectroscopic and other experiments.

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.

Since the New Horizons flyby, scientists have advocated for an orbiter mission that would return to Pluto to fulfill new science objectives.

The last objective could be accomplished using laser pulses to generate a complete topographic map of Pluto. New Horizons principal investigator Alan Stern has advocated for a Cassini -style orbiter that would launch around the th 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.

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.

Higher southern latitudes have only been observed, at very low resolution, from Earth. This is enough to show the extent of the temperate-zone maculae.

Later images had slightly better resolution, due to minor improvements in Hubble instrumentation, but didn't reach quite as far south. From Wikipedia, the free encyclopedia.

Pluto orbits in a far-out region of the solar system called the Kuiper rhymes with viper Belt. There are lots of icy, rocky objects out there.

But they are so far from the sun they are really hard to see, even with powerful telescopes. Pluto, once considered the ninth and most distant planet from the sun, is now the largest known dwarf planet in the solar system.

It is also one of the largest known members of the Kuiper Belt , a shadowy zone beyond the orbit of Neptune thought to be populated by hundreds of thousands of rocky, icy bodies each larger than 62 miles kilometers across, along with 1 trillion or more comets.

Methane and nitrogen glaciers on Pluto expand and "grow" in response to temperature changes on the dwarf planet, new research suggests.
