10th planet in our Solar System found ?!?!?!

[Mike]

Astronomers have found a large object in the Solar System's outer reaches. It is being hailed as "a great discovery".

Details of the object are still sketchy. It never comes closer to the Sun than Neptune and spends most of its time much further out than Pluto.

What happened to Sedna?

[Whitters]

As for Sedna, or even Pluto for that it would appear that they would be better described as  Kuiper belt objects.

Empherisis for planet X, CCD folks should pick it up.
