Astronomers have observed diverse features and characteristics of Pluto, which include mountains, valleys, and plains on its surface, a notable heart-shaped region named Tombaugh Regio, a delicate atmosphere made up of methane, nitrogen, and carbon monoxide, as well as multiple small moons such as Charon, Nix, Hydra, Kerberos, and Styx. The planet showcases past cryovolcanism geologic activities that involve icy materials, and on its surface, it harbors water ice, nitrogen ice, and different volatile compounds.
Some observable characteristics of Pluto are its size (Pluto is the smallest and most distant of the eight planets in our solar system), its composition (Pluto is composed of rock and ice), its orbit (Pluto has an elliptical orbit and takes 248.5 years to orbit the sun), its surface features (Pluto has a very dark surface with few visible features), and its moons (Pluto has five known moons).
