Solar System
Our planetary system includes the Sun, eight planets, their moons, and smaller bodies. Kepler's laws describe how planets orbit the Sun in ellipses, with the Sun at one focus.
Stars & Galaxies
Stars are born in nebulae, spend most of their lives on the main sequence, and eventually evolve into red giants, white dwarfs, or more exotic objects. Galaxies contain billions of stars.
