PlUTO

Dwarf Planet: Pluto was once considered the ninth planet in our solar system but was reclassified as a dwarf planet in 2006 by the International Astronomical Union (IAU). It is located in the Kuiper Belt, a region beyond Neptune's orbit.

Characteristics: Pluto has a rocky core surrounded by a thin atmosphere primarily composed of nitrogen, with traces of methane and carbon monoxide. It has five known moons, the largest of which is Charon, and its surface is covered in frozen nitrogen, methane, and carbon monoxide. Pluto's orbit is highly elliptical, and it takes about 248 Earth years to complete one orbit around the Sun.

Charon and Other Moons: Pluto has five known moons, with Charon being the largest and most well-known. Charon is so large relative to Pluto that they are sometimes considered a "binary system." The other moons of Pluto are Nix, Hydra, Kerberos, and Styx.
