A person who studies heavenly bodies is called an astronomer.

Astronomers study celestial objects such as stars, planets, galaxies, and other phenomena in outer space. They use telescopes, satellites, and other instruments to observe and analyze these objects, as well as mathematical models and computer simulations to understand their behavior and properties. Astronomers may specialize in areas such as astrophysics, cosmology, planetary science, or observational astronomy. Their research helps us to better understand the universe and our place within it.
