PLANETARY SCIENCE
Planetary science is the scientific study of planets, celestial bodies and planetary systems and the
processes of their formation. It studies objects ranging in size from micrometeoroids to gas giants,
aiming to determine their composition, dynamics, formation, interrelations and history.
Planetary scientists work to improve our understanding of the planets, satellites and smaller bodies
in the solar system through:
- Studying the atmospheres, surfaces and
interiors of planets
- Understanding the origins of planets and
the physical processes at work,
- Using radar to determine the physical
characteristics of asteroids and to search
for asteroids that may pose a hazard to
Earth
