To become an astronomer, studying both mathematics and physics is essential, as these subjects provide the foundational knowledge needed in the field. The distinction between astronomy and astrophysics is often unclear, with astronomy focusing more on observational and practical aspects, while astrophysics delves into theoretical concepts, particularly concerning stellar phenomena. Many professionals in astronomy have degrees in physics or mathematics, highlighting the importance of these disciplines. A solid understanding of physics and math allows for application across various branches of astronomy. Overall, pursuing a combination of physics and mathematics is recommended for aspiring astronomers.
