To orbit is to follow a circular or elliptical path around a central body. Usually a planet, moon or satellite is described as orbiting, but a child who has too much sugar can sometimes orbit around his parents in an annoying fashion.
Orbit comes from the Latin orbita, “course,” or “track.” The verb orbit is the act of revolving around another object, usually on a circular or elliptical course. Many planets, moons, stars, meteors spacecraft and other objects in outer space orbit around each other. Electrons also orbit around the nucleus of an atom. The noun orbit is the path the object in orbit takes: "The Earth’s orbit around the Sun takes one year to complete."
