Summary

If you're looking for a planet, you'll probably find one...but you might not call it a planet later.

For 62 years Pluto was the oddball: a strange orbit, a strange surface, way out there all alone.

Over 1000 objects have been found in the Kuiper Belt in the last 14 years, and we're only seeing the tip of the iceberg.

The Pluto situation now bears a striking resemblance to the asteroid situation 150 years ago.

The need for the IAU's definition was rushed by the discovery of Eris.

• Many astronomers angry and upset...

• ...but using orbital criteria might not be a bad idea if it's well defined.
