Gravity and Orbits
Gravity is the force that keeps planets, moons, and other objects in orbit around a larger, more massive body: it constantly pulls the orbiting object inward, while the object's own forward motion keeps it from simply falling straight in, resulting in a curved, roughly circular path. This same force holds the solar system together around the sun and holds galaxies like the Milky Way together as well.
