24007 Nixon

24007 Nixon or 8522 US is a mid-planetoid in outer Solar System, Nixon has a very small asteroid oribiting around it, however, this planet was invaded by unknown alien race 200 years ago.

ZIM's arrival
Although that Nixon's isn't ZIM's target, ZIM finds Nixon interesting, he once even built a base on it. This means that Nixon is now ZIM's but not the alien race that existed 200 years ago.

In other cases ZIM once tried to send Nixon to Earth to destroy it, it wasn't really going well.
