orbital period

(length of time for an orbiting object to complete one cycle)

An orbital period is the length of time for an orbiting object to make one circuit around the body it is orbiting. The time unit year is (basically) the Earth's orbital period. Variants of the concept:


(orbits,celestial mechanics,period)
