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.
The concept of a 24 hour day cannot be extended to Venus or Mercury as it is to Earth and Mars. On Earth, there is only a tiny difference between rotational time and solar timâ¦e. On Venus, the difference between the sidereal day (243 Earth days) and the solar day (117 Earth days) makes clock times meaningless. A rotational day on Venus takes about 5832 Earth hours. A sunrise-to-sunrise day takes about 2802 Earth hours. Using either to design a clock would not be practical.
