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 takes over 10,000 years to orbit, and during the next 50 years it will slowly move closer to the Sun as it comes to perihelion at a distance of 76 AU from the Sun. [3] Sedna is the largest known sednoid, a class of objects that play an important role in the Planet Nine hypothesis. Pluto (30–49 AU, about 34 AU in 2015) was the first Kuiper ...
In effect, each orbits the other, forming a binary system informally referred to as a double-dwarf-planet. Pluto's four other moons, Nix, Hydra, Kerberos and Styx are far smaller and orbit the Pluto–Charon system. [5] Among the other dwarf planets, Ceres has no known moons.
Charon and Earth’s moon are both a large fraction of the size of the main body they orbit, which is unlike other smaller moons orbiting planets throughout our solar system. (Pluto has four ...
Areocentric orbit (named after Ares): An orbit around the planet Mars, such as that of its moons or artificial satellites. For orbits centered about planets other than Earth and Mars and for the dwarf planet Pluto, the orbit names incorporating Greek terminology are not as established and much less commonly used:
This is a list of trans-Neptunian objects (TNOs), which are minor planets in the Solar System that orbit the Sun at a greater distance on average than Neptune, that is, their orbit has a semi-major axis greater than 30.1 astronomical units (AU). The Kuiper belt, scattered disk, and Oort cloud are three conventional divisions of this volume of ...
Space is very big and quite often, very weird. Last week, an image captured by NASA's Reconnaissance Orbiter looked just like a bear, and "The Green Comet" reached its closest point to Earth in ...
