<img src="http://scienceblog.com/community/images/topics/topicspace.gif" align="right" hspace="8" />A new moon of the planet Uranus has been discovered and confirmed by a team of astronomers at NASA's Jet Propulsion Laboratory. This most-recently discovered natural satellite, named S/2001 U 1, brings the total number of confirmed uranian moons to 21. The new kid on the block --- and five others like it --- have very irregular, eccentric orbits that don't share the same orbital plane as the larger moons of Uranus. Ranging in size from 10 to 20 kilometers, these moons are thought to be remnants of ancient collisions that occurred at the early stage of planetary formation.
