Astronomy and Astrophysics Major Requirements

Requirements for the B.S. in Astronomy and Astrophysics

Flowchart for Astronomy and Astrophysics Major Courses

Curriculum

The Astronomy Department has adopted the following curriculum for the Astronomy & Astrophysics Major:

General Education (GE) Requirements

All students completing Astronomy and Astrophysics as their primary major must complete the GE requirements for a Bachelor of Science degree from the College of Arts and Sciences (ASC), which are detailed here. Students who began at Ohio State in the Summer of 2022 or earlier will follow the Legacy GE (or GEL), whereas students who began at Ohio State in the Autumn of 2022 or later will follow the New GE (or GEN).

If your primary major is in a different college and/or if your primary major does not result in a Bachelor of Science degree, then the GE requirements for your degree may be different. Please consult with the academic advisor for your primary major for clarification on your GE requirements.
