Gravitational forces as described by Newton's Universal Law of Gravitation. Also important is the inertia of the planets and Newton's First Law of Motion is involved there.
Moons orbit planets. Planets orbit stars. Some stars orbit other stars, or orbit their mutual center of gravity. Stars orbit the center of the galaxy. Galaxies may orbit the center of the "galactic group".
