Hubble spots moon around third largest dwarf planet

Another dwarf planet at the edge of the Solar System has been found to have a small companion moon. The world, named 2007 OR10, is the third largest dwarf planet that we know about — around 955 miles wide. The discovery was made possible by three NASA space telescopes, and it means we have found moons around practically every large dwarf planet more than 600 miles across in our cosmic neighborhood. Astronomers started to think 2007 OR10 might have a moon after NASA’s Kepler Space Telescope showed that the dwarf planet was rotating more slowly than usual. Typically, objects in the Kuiper Belt — the large cloud of icy bodies beyond Neptune where this dwarf planet resides — take less than 24 hours to rotate. But Kepler found that 2007 OR10...
