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.
The climate of Pluto concerns the atmospheric dynamics, weather, and long-term trends on the dwarf planet Pluto. Five climate zones are assigned on the dwarf planet: tropics, arctic, tropical arctic, diurnal, and polar. [ 1] These climate zones are delineated based on astronomically defined boundaries or sub-solar latitudes, which are not ...
Earth is rounded into an ellipsoid with a circumference of about 40,000 km. It is the densest planet in the Solar System. Of the four rocky planets, it is the largest and most massive. Earth is about eight light-minutes away from the Sun and orbits it, taking a year (about 365.25 days) to complete one revolution.
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 ...
10 -5 -10 -6 %. 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 ...
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.
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.
This is a list of named geological features on Pluto, identified by scientists working with data from the New Horizons spacecraft. The International Astronomical Union (IAU) officially approved the first 14 names on 8 August 2017 (announced 7 September 2017), [ 1] with additional names following in each subsequent year, but many of the names ...
