Although now reclassified as a dwarf planet, Pluto is the center of a small world of its own. In addition to its large moon Charon, two more, shown above, were spotted by the Hubble Space Telescope in 2005.

To learn about the controversy over Pluto's status, see NASA's Much Ado About Pluto and also Caltech astronomer Mike Brown's commentary.
