This is very cool: a competition has been set up to allow school kids to suggest names for the small solar system bodies that orbit beyond Neptune!
The competition has been OKed by the International Astronomical Union, which has a subcommittee that names such objects. The ages groups for submissions are divided up into ages 1-11, 12+, and school groups.
Emily at The Planetary Society Blog has more details as well. If you're a teacher or student, then you definitely should jump in; this will make a great school project. But hurry: the competition closes on May 30, so get naming!
