  2. Pluto - Wikipedia

    en.wikipedia.org/wiki/Pluto

    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.

  3. Hydra (moon) - Wikipedia

    en.wikipedia.org/wiki/Hydra_(moon)

    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]

  4. Nix (moon) - Wikipedia

    en.wikipedia.org/wiki/Nix_(moon)

    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 ...

  5. Moons of Pluto - Wikipedia

    en.wikipedia.org/wiki/Moons_of_Pluto

    Moons of Pluto. The dwarf planet Pluto has five natural satellites. [1] In order of distance from Pluto, they are Charon, Styx, Nix, Kerberos, and Hydra. [2] Charon, the largest, is mutually tidally locked with Pluto, and is massive enough that Pluto and Charon are sometimes considered a binary dwarf planet.

  6. Atmosphere of Pluto - Wikipedia

    en.wikipedia.org/wiki/Atmosphere_of_Pluto

    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 ...

  7. Geography of Pluto - Wikipedia

    en.wikipedia.org/wiki/Geography_of_Pluto

    Geography of Pluto. The geography of Pluto refers to the study and mapping of physical features across the dwarf planet Pluto. On 14 July 2015, the New Horizons spacecraft became the first spacecraft to fly by Pluto. [1][2] During its brief flyby, New Horizons made detailed geographical measurements and observations of Pluto and its moons. [3]

  8. Kuiper belt - Wikipedia

    en.wikipedia.org/wiki/Kuiper_belt

    The Kuiper belt (/ ˈkaɪpər / KY-pər) [1] is a circumstellar disc in the outer Solar System, extending from the orbit of Neptune at 30 astronomical units (AU) to approximately 50 AU from the Sun. [2] It is similar to the asteroid belt, but is far larger—20 times as wide and 20–200 times as massive. [3][4] Like the asteroid belt, it ...

  9. Geology of Pluto - Wikipedia

    en.wikipedia.org/wiki/Geology_of_Pluto

    Geology of Pluto. The geology of Pluto consists of the characteristics of the surface, crust, and interior of Pluto. Because of Pluto's distance from Earth, in-depth study from Earth is difficult. Many details about Pluto remained unknown until 14 July 2015, when New Horizons flew through the Pluto system and began transmitting data back to ...
