Pluto -- Pluto was discovered in 1930. Scientists thought that Pluto was the same size as Earth but then they took a closer look at it and they found out that it was very tiny. Pluto has four natural satellites named Charon, Nix, Hydra and P4. Charon was discovered in 1978 by James Christy. Nix and Hydra were discovered in 2005. And S/2011P1 also known as P4 was discovered in 2011 with a Hubble space telescope.

They also planned for New Horizon to go past Pluto to the Kuiper Belt. It should reach the Kuiper belt around 2026. Some pieces of rock and ice “mini planets” are like Pluto because they are all far from the sun and they are really cold. The scientists think that some of the rocks may be as large as Pluto and Charon. Scientists think that the sloar system began as a spinning cloud of gases and...
