A sidereal day on Mars is the length of time that it takes the planet to rotate once on its axis. A sidereal day on Mars lasts 24 hours 37 minutes and 22 seconds. The solar day is how long it takes the Sun to return to the meridian.
A Mars solar day has a mean period of 24 hours 39 minutes 35.244 seconds, and is customarily referred to as a sol in order to distinguish this from the roughly 3% shorter solar day on Earth.
