What Do You Call a Person Who Studies Space?
A person who studies space is called an astronomer or astrophysicist. These types of scientists are responsible for the discovery of all of the planets, stars, asteroids and other extraterrestrial objects.
An astronomer works to locate objects and measure their magnitudes and motions, searching to find what they are made of and how they create their light. Astronomy is one of the oldest sciences. Astronomers of the earliest civilizations performed methodical observations of the night sky, hoping to find signs to explain or support theories and ideas that may have been formulated. Astrophysics is the branch of astronomy that deals with the physics of the universe, such as the physical properties of celestial objects. Astronomers typically collect observational data.
