This Asteroid Will Be Earth's Second Moon

Does Earth have two moons? In April 2016, scientists discovered a new neighbor that appears to have been around for a hundred years and will remain for another few centuries. The asteroid, called 2016 HO3, is a quasi-satellite in Earth's orbit that can almost be considered a second moon. This asteroid is in orbit around the sun, but it circles around Earth at the same time. Paul Chodas, manager of NASA's Center for Near-Earth Object (NEO) Studies at the Jet Propulsion Laboratory, described 2016 HO3, which is much too far from our home planet to be considered a true moon or natural satellite, as being "caught in a little dance with Earth." The asteroid, which measures only about 40-100 meters across, will cause no threat to our planet. We've collected some awesome videos on this topic. Watch them now to learn more.
