A planet's year length depends on its distance from the Sun. Planets closer to the Sun have shorter years. A planet's rotation speed is unrelated to its year length. Planets' orbital speeds vary ...

Saturn takes about 29.4 Earth years to complete one orbit of our home star, according to NASA. As it does, the second largest planet in our solar system experiences seasons due to the axis of rotation ...
