Keeping Up With the Outer Solar System

In late March I mentioned that Caltech's Mike Brown was looking for a name for the satellite of Pluto. He's picked one so be sure to visit Mike Brown's Planets to find out what name was chosen and why.
Speaking of Mike Brown, he has been looking for more objects like Sedna but none have been found yet and that is telling about the solar system. He has also published some work on Haumea and its satellites.
