How long is a day on Saturn? This figure was hard to calculate because the gas giant does not have a solid surface and a magnetic field makes the rate of rotation hard to see. But now scientists have used data from Cassini to pin down a final answer: a day is ten hours, 33 minutes, and 38 seconds long.
