NASA Discovers Earth Has Two Moons

In 2016, NASA astronomers detected a high-orbit object which appeared to be orbiting the Earth. While many small asteroids and pieces of man-made debris orbit the Earth, the size of this object technically classifies it as a satellite similar to our moon. Based on NASA’s estimates, the asteroid is somewhere between 120 feet (40 meters) and 300 feet (100 meters) in diameter. According to NASA’s Jet Propulsion Laboratory, the asteroid, named 2016 HO3, has been orbiting Earth for centuries and will continue to circle our planet for several more.
