Poor little Pluto. In 2006 astronomers ganged up on it and voted to strip it of its planethood—but other astronomers signed a petition saying they'd ignore that vote.
Now Pluto itself seems to be fighting back. Thanks to the Hubble Space Telescope, we’ve learned that Pluto has at least five moons—pretty impressive for something that's supposedly not a planet. And new research suggests Pluto is just what we were taught long ago: the largest world orbiting the sun beyond Neptune.
