How long are Mars years and days?

Answer 1

1year on Mars is 687 days. 1 day on Mars is 24 hours and 37 min.
One day on mars is 24h 39m 35.244s a sidereal day (full rotation) is about 2 minutes longer

One martian year is about 686.98 Earth days

Answer 2

One Mars day is 1 Earth Day and 37 Minutes, about. One Year is 687 Earth days. Also here's some other Facts: The Diameter Of Mars is 4,223 miles (6,796 km). It has two moons. It is on average about 142,000,000 miles from the Sun (228,000,000km). It is 60 Degrees Fahrenheit (20 Degrees Celsius), and The Atmosphere is made up of Carbon Dioxide and Nitrogen, mainly.

Edit : The average temperature on Mars is MINUS 20 degrees Celsius, or even

colder.

Also the "day" you mean is obviously the time Mars takes to rotate. That's

correct, but there's also the "solar day" which is a couple of minutes longer.
Since the Mars year equals approximately 687 Earth days and a Martian day equals approximately 24.62 earth hours (and, the Earth day equals 24 hours), the math is simple: 687 * 24 / 24.62 = 669.699 ~ 669.7. The Martian year is 669.7 Martian days long.
It takes Mars 686.98 days to orbit the Sun.

A Mars day is 24.7 hours.
Day = 24 hrs 37 min approximately. That's the rotation period, known as the

sidereal day. There's also the solar day which is a couple of minutes longer.

Year = 687 Earth days.
