Two New Saturnian Moons

Mixel writes "NASA's Cassini spacecraft, which has been orbiting saturn since the 30th of June has uncovered two previously unknown bodies. 'The moons are approximately 3 kilometers (2 miles) and 4 kilometers (2.5 miles) across -- smaller than the city of Boulder, Colorado.' The Huygens probe will be deployed to the large (bigger than Mercury!) yet mysterious moon, Titan, in December."

I'd say it's a moon when it's big enough to exert enough gravity to walk on, without worrying about being flung out into space.

Moons orbit planets, asteroids orbit the sun.
There does need to be some cutoff at where something is considered a moon and where its just a rock going around a planet, otherwise all the stuff in Saturn's ring could be considered moons... hmm maybe I could name one "Servognome" and request a goverment grant of $50,000 to study the rock^H^H^H^H moon.
I think all this classification stuff probably has to do with how scientists can get more grant money. Kinda how there are 6 great lakes
