titan is the natural satellite of which planet?
europa
most regular moons (natural satellites following relatively close and prograde orbits with small orbital inclination and eccentricity) in the solar system are tidally locked to their respective primaries, meaning that the same side of the natural satellite always faces its planet. the only known exception is saturn's natural satellite hyperion, which rotates chaotically because of the gravitational influence of titan.
natural satellite
many authors define "satellite" or "natural satellite" as orbiting some planet or minor planet, synonymous with "moon" – by such a definition all natural satellites are moons, but earth and other planets are not satellites.









































a few recent authors define "moon" as "a satellite of a planet or minor planet", and "planet" as "a satellite of a star" – such authors consider earth as a "natural satellite of the sun".
