The Footprints on the Moon Will Be There for 100 Million Years

The footprints on the Moon will be there for 100 million years unless we go and clean them up. I read a fact that it was like two or three years ago, a giant asteroid the size of the one that killed the dinosaurs, passed closer to Earth than the Moon is distant from Earth. Scientists didn't know about it until after it had passed. And all the scientists were like, well, but space. It's a great, great mystery. The great beyond maybe we should keep having space.
