Coat hooks are everywhere in hotels or even in public restrooms. They serve their purpose well by letting you hang your things while you are doing your business.

We've always thought that the Earth just had one moon. However, National Aeronautics and Space Administration (NASA) scientists have revealed that the Earth has had a second, mini-moon for the past 100 years. The NASA team, however, only spotted it last April.

This second moon is actually a recently captured asteroid that the scientists are calling it "2016 HO3." As far as heavenly bodies go, it's relatively small. It measures 120 feet long and 300 feet wide. This explains why it took so long for scientists to discover its presence.

The "mini-moon" was discovered last April.
