The rotational period of an object in the solar system is the amount of time it takes for the object to complete one turn, or rotate on its axis. In addition to rotational movement, the bodies in our solar system also move around, or orbit, other bodies.Planets orbit the Sun while moons orbit around planets.The amount of time required for a planet or moon to complete one orbit around another body is called an orbital period. On Earth, we call this orbital period a year. Our year is 365.256 days.On Mars it takes 686.98 days (Earth days, that is) to complete one orbit about the Sun--that's a long time to wait between birthdays!lanets orbit the Sun while moons orbit around planets.
