Planetary Science

Planetary science encompasses the study of the physical and chemical nature of planetary bodies, both in the Solar System and in extrasolar systems. The formation of planets, the forces that sculpted their orbits, the processes that shaped their interiors, surfaces, and atmospheres, and the development of life all fall under its rubric. Understanding these complex phenomena requires knowledge of astronomy & astrophysics, earth science, meteorology, atmospheric science, space science, plasma physics, chemistry, and biology.

A Planetary Science major has been developed to study the remarkable interface between the two separate disciplines of Earth and Planetary Science and Astronomy. In EPS the student will receive more training in geology/geophysics/atmospheric sciences, while in astronomy, planetary science is studied via remote sensing (astronomy). The growing interest in this interdisciplinary field is illustrated by the activities of the Center for Integrative and Planetary Science (CIPS) (
