Characteristics of Pluto
- Size: Pluto is smaller than Earth's moon, with a diameter of approximately 2370 kilometers.
- Orbit: It has an eccentric orbit that is tilted relative to the plane of the solar system, causing it to sometimes be closer to the sun than Neptune.
- Atmosphere: Pluto has a thin atmosphere primarily composed of nitrogen, with traces of methane and carbon monoxide.
- Moons: Pluto has five known moons, the largest of which is Charon.
- Surface: Its surface is composed of rock and ice, with regions of frozen nitrogen and methane.
