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.
New Horizons data suggest equally variable surface ages for Pluto, with ancient, dark, mountainous terrain occurring alongside the bright, flat, effectively craterless Sputnik Planitia and various terrains of intermediate age and color. Pluto's surface color changed between 1994 and 2003: the northern polar region brightened and the southern ...
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 ...

The vast majority (97.3%) of minor planets are asteroids from the asteroid belt (the catalog uses a color code to indicate a body's dynamical classification). There are more than a thousand different minor-planet discoverers observing from a growing list of registered observatories.
