Chinese astronomy is the study of stars and the universe by the people of ancient China. Ancient Chinese astronomers looked up in the night sky and watched the stars, planets, and comets moving across the sky. They kept track of where the stars and planets moved and studied the patterns they made. They also observed meteor showers, supernovas, and eclipses. Ancient Chinese astronomers kept detailed records of their observations to help them better understand the sky and created a system of constellations of stars. They also used their observations to tell time, make predictions about the weather, and even plan events or ceremonies for the Emperor.
