Astronomers claim discovery of 10th planet

From USA Today:

LOS ANGELES (AP) — Astronomers announced Friday that they have discovered a new planet larger than Pluto in orbit around the sun.

The discovery in the outlying regions of solar system was made with the Samuel Oschin Telescope at the Palomar Observatory, planetary scientist Mike Brown of the California Institute of Technology said in a statement.

Details were being released in a conference call with reporters Friday afternoon.

The unnamed planet would be the 10th in the solar system, although there are scientists who dispute the classification of Pluto as a planet.

Isn't this about the 5th time they've found a 10th planet in our solar system? I could swear I hear about this every couple of years. Still, it is fascinating stuff and I have never understood how an astronomer can look at a fuzzy dot and proclaim it a planet.
