Here's why:
* Venus has a very slow rotation, taking approximately 243 Earth days to complete one rotation. This is longer than its orbital period around the sun, which is 225 Earth days.
* Mercury rotates much faster than Venus, completing a rotation in about 59 Earth days.
* Mars has a rotational period of about 24.6 hours, very similar to Earth's.
* Jupiter rotates incredibly quickly, completing a rotation in about 10 hours.
