Dwarf Planets

Pluto was discovered in 1930 by Clyde W. Tombaugh. It was origionally the ninth planet in our Solar System. Recently it's status changed to a Dwarf Planet.



Pluto's equatorial radius is 1,137 km, which is small for a planet and it's orbiting period is 248.54 years. Pluto was changed to be a Dwarf Planet because of the size of its orbit .It was too small overall. Pluto is Grey/Blue and it is made from rocks and ice.

Pluto has three moons called Charon, Nix and Hydra. The biggest moon of Pluto is Charon, it's half the size of Pluto. Charon was discovered in 1978. Some other Dwarf Planets are Ceres, Hauma, Eris and Makemake. Pluto's temperachure is usally around - 230 degrees celcies. Pluto is very cold because it is 5,913,520,000km away from the Sun.

That's why Pluto was changed to be a Dwarf Planet.
