One is the loneliest number, especially when you are a single moon circling the planet full of humans. But let’s not lose hope here because NASA just announced that there might be a second moon come to keep you company. This newly discovered moon is smaller than our moon and goes around the Earth astonishingly irregularly, but still, two is quite better than one. This second “moon,” is actually an asteroid called 2016 HO3 and it is currently locked into “a little dance” with Earth. It's being called as "Quasi-Moon".
