- Numbers of stars in the universe: 160,000,000,000,000,000,000,000 (you can also say 160 septillion)
- Did you know that if you filled up a standard olympic-sized swimming pool with sand, and counted each grain of sand, that would be approximately how many stars are in our Milky Way Galaxy
- Did you know there are most stars in the universe than there is sand on all the beaches on Earth?
