Astronomers have discovered whan can be the 10th planet of our solar system.

BBC News Science/Nature reports in an article called Astronomers discover "new planet" that it was dicovered with the help of the space telescope Spitzer. It was also registered by the Hubble telescope.

Sedna is 2,000 km about. It is named after the sea goddess of the Inuits. Sedna is the greatest object in our solar system since the discovery of Pluto in 1930.
