How much longer is a Martian year?

The Earth zips around the Sun at about 67,000 miles per hour, making a full revolution in about 365 days – one year on Earth. Mars is a little slower, and farther from the sun, so a full circuit takes 687 Earth days – or one Mars year. That longer year means longer seasons too.

How long is a Martian day known as a sol?

24 hours, 39 minutes and 35 seconds Mars is a planet with a very similar daily cycle to the Earth. Its sidereal day is 24 hours, 37 minutes and 22 seconds, and its solar day 24 hours, 39 minutes and 35 seconds. A Martian day (referred to as “sol”) is therefore approximately 40 minutes longer than a day on Earth.

What happens in each Martian year?

The Martian year comprises 668.59 Martian days – or sols (equivalent to 687 Earth days or 1.88 Tropical Earth years). Each sol is 24.623 hours (24 hours and 37 minutes) in length, i.e. 37 minutes longer than a day on Earth.
