Heavenly bodies are the things that make up the universe, such as stars, planets and smaller objects. Within these categories are many different variations instead of one single type.
Stars include small red dwarfs, even smaller neutron stars, and stars larger than the Earth's Sun. These are large, gaseous objects that emit light that can be seen in the sky. Planets come in various shapes and sizes, such as the gas giant Jupiter, ringed Saturn, water-covered Earth and rocky Mercury. Smaller items include moons, comets and asteroids. Moons are linked with planets, while comets and asteroids float more freely throughout galaxies and solar systems.
