NASA sponsored astronomer Michael Brown of CIT just announced he have found a 10'th planet.
The claim was made for one object based on its brightness alone and that for one object at 3 times the distance of Pluto. In short its smack in the middle of the belt of other KBO's. The guy claim he was forced to reveal his data since a hacker had threatened to release information about the object. Im strongly unconvinced about that story. Why then claim it to be a planet rightoff. More likely think this guy must be looking for the fame of Clyde Tombaugh. Without any infrared measurements or to establish the albedo properly which would have given a guesstimate of the objects size he singlehandedly claim a KBO planet, this should get the Bad astronomy 1'st price prize for preposterous extrapolation from a single unconvincing piece of scientific data.
