How many Earth hours is in one Mars day?
The simple answer is "just over 24 hours".
A day on Mars is 24 hours, 39 minutes and 35 seconds
That's the "solar day". The rotation period or "sidereal day" is
a couple of minutes less.
For comparison, on Earth the solar day is 24 hours and the sidereal day is about 23 hours and 56 minutes.
Mars rotates every 24.62296 earth hours. 1.02595675 Earth days so basically its about the same length of an earth day except by a fraction 148,000,00 24 hours 37 minutes 24hours 37minutes solar day is 24 hours 39 minutes 35.244 seconds Mars has a similar day length to Earth, a little longer at 24h 39m 35s (apparent solar day).
Mars' period of rotation on its axis is 24.6 hours, so its day is about 36 minutes longer than an earth day. So there would be 41 days on Earth in the same time as 40 days on Mars. If you were working on Mars, you probably would not notice the difference, as you would be taking care of many other things.
A day on Mars (the time it takes to rotate on its axis) is 24.62 hours, just slightly longer than a day on Earth. A year on Mars (the time it takes to go around the Sun) is 686.97 days, almost 2 of our Earth years. A day on Mars is 24 hours, 39 minutes and 35 seconds; amazingly similar to a day on Earth. This is just one of the reasons that space enthusiasts…
