Heliocentric orbit

A heliocentric orbit (also called circumsolar orbit) is an orbit around the Sun. In our Solar System, all planets, comets, and asteroids are in such orbits, as are many artificial probes and pieces of debris. Ganymede, by contrast, is not in a heliocentric orbit as it orbits Jupiter. An interior heliocentric orbit is an orbit inside the orbit of the Earth, for example the orbit of Venus. An exterior heliocentric orbit is an orbit outside the orbit of the Earth, for example the orbit of Mars.

The helio- prefix is derived from the ancient Greek word helios, meaning "sun", and also Helios, the personification of the Sun in Greek mythology.^[1]
