Nasa finds Planet X

For once Jasper has been beaten to it...

The object has been named Sedna, after the Inuit goddess of the ocean.

The body is believed to be about 1,250 miles across, but may even be larger than the furthest known planet, Pluto, which was discovered in 1930 and has a diameter of 1,406 miles.

Scientists believe Sedna is 6.2bn miles from Earth, in a region of space known as the Kuiper Belt, which contains hundreds of other known bodies."
