Planetarium software

Planetarium software is a type of computer program that is designed to help you learn about the night sky. It shows you what stars, planets, constellations and other objects look like in the sky at any given time. It can also provide information about the objects it shows, such as their size, distance, and other interesting facts. Many planetarium programs allow you to travel through time to see how the sky will look in the future and past.
