Moon spotted around Solar System's 3rd largest dwarf planet
NASA announced spotting a moon orbiting Solar System's third largest dwarf planet, 2007 OR10. The discovery was made by NASA's Hubble Space Telescope in the Kuiper Belt, a belt of icy debris from Solar System's formation 4.6 billion years ago. The dwarf planet follows an eccentric orbit, but is three times farther than Pluto is from the Sun, NASA said.
