A star party is when a group of people get together to look at the stars and planets in the sky. They usually go to a place where there aren't many lights so they can see the stars really well. They bring telescopes and sometimes binoculars to help them see things better. They also bring warm clothes and snacks to make sure they are comfortable while they look at the sky. Everyone gets to take turns looking through the telescopes and pointing out cool things they see. It's like having a big sleepover with your friends, but instead of watching movies, you are watching the stars!
