He does not have a car and does not drive our family car (yet.) He Dorms in Yeshiva and is not usually home. I contacted my insurance company just to ASK how much it would cost to add him to my insurance, to decide if I would allow him to drive our car.
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.
We would use the Local Solar Day no matter which planet we were on, and refer to it locally as a Sol. The average length of a Martian solar day is 88,775.24409 seconds or 24 hours, 39 minutes, 35.24409 seconds versus Earth's 24 hours. The conversion factor is 1.0274912510:1. Mars' solar day is only about 2.7% longer than that of the Earth.
