Earth Has a 2nd Moon?! Meet PT5

Did you know that Earth has a temporary second moon? PT5 is a 33-foot wide rock that normally orbits the Sun. But it’s close enough to Earth that our gravity has pulled it into a partial path around our planet, where it will remain for about 2 months before returning to orbiting the Sun. Because it’s so small, PT5 will not be visible to the naked eye, but it can be seen with a good telescope!
