New moon found circling Pluto

2011-07-20 22:38

Houston - Distant and tiny Pluto has been hiding something from Earth: another moon.

Nasa announced on Wednesday that the Hubble Space Telescope has found a fourth moon circling Pluto, which had been demoted from full planet to dwarf planet. Astronomers had been looking to see if Pluto had a ring, but instead they found another object circling the dwarf planet that is 4.8bn km from Earth.

But it is a mini-moon. It is only eight to 33km wide. Pluto's biggest moon, Charon, is 80 times bigger. The other two moons are Nix and Hydra.

Until astronomers decide a name, this moon is called P4.

      Are they clinging on to the ring around Uranus?

    Great another "discover" which once again highlights how much we as children were taught as fact that is in reality someones opinion, also the Hubble telescope has been in orbit for years what took so long to find this moon
