Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond the orbit of Neptune. It is the ninth-largest and tenth-most- massive known object to directly orbit the Sun. It is the largest known trans-Neptunian object by volume, by a small margin, but is less massive than Eris.
Hydra orbits the Pluto-Charon barycenter at a distance of 64,738 km (40,226 mi). [10] Hydra is the outermost moon of Pluto, orbiting beyond Kerberos. [11] Similarly to all of Pluto's moons, Hydra's orbit is nearly circular and is coplanar to Charon's orbit; all of Pluto's moons have very low orbital inclinations to Pluto's equator. [11]
The atmosphere of Pluto is the layer of gasses that surround the dwarf planet Pluto. It consists mainly of nitrogen (N 2), with minor amounts of methane (CH 4) and carbon monoxide (CO), all of which are vaporized from surface ices on Pluto 's surface. It contains layered haze, probably consisting of heavier compounds which form from these gases ...
K.B. (brother) Pluto is an American cartoon character created by the Walt Disney Company. He is a yellow-orange color, medium-sized, short-haired dog with black ears. Unlike most Disney characters, Pluto is not anthropomorphic beyond some characteristics such as facial expression. [3] He is Mickey's pet.
The definition of a planet has been a hot topic ever since a change kicked Pluto out of our planetary lineup in 2006. Now, a group of researchers is proposing a new definition yet again—one with ...
Clyde William Tombaugh / ˈtɒmbaʊ / (February 4, 1906 – January 17, 1997) was an American astronomer. He discovered the ninth planet Pluto in 1930, the first object to be discovered in what would later be identified as the Kuiper belt. At the time of discovery, Pluto was considered a planet, but was reclassified as a dwarf planet in 2006.
Tombaugh Regio (/ ˈ t ɒ m b aʊ ˈ r ɛ dʒ i oʊ /), sometimes nicknamed "Pluto's heart" after its shape, [2] is the largest bright surface feature of the dwarf planet Pluto. [3] [4] [5] It lies just north of Pluto's equator, to the northeast of Belton Regio and to the northwest of Safronov Regio, which are both dark features. [6]
Nix is a natural satellite of Pluto, with a diameter of 49.8 km (30.9 mi) across its longest dimension. [3] It was discovered along with Pluto's outermost moon Hydra on 15 May 2005 by astronomers using the Hubble Space Telescope, [1] and was named after Nyx, the Greek goddess of the night. [10] Nix is the third moon of Pluto by distance ...
