Planetary Science And Solar System Astronomy

This group collects the Astronomy subcategory's members whose defining work concerns the Solar System: planets, moons, asteroids, comets and exoplanets orbiting other stars, from the classical astronomers who first mapped planetary motion to the modern planetary scientists who discovered new worlds. It is the subcategory's largest group, kept apart from Stellar Astronomy And Astrophysics, whose members study stars themselves rather than planetary bodies.
