A planet's day is the time it takes the planet to rotate or spin once on its axis. Mars rotates at almost the same speed as the Earth so a day on Mars is about as long as a day on Earth. A day on Mars is 24.62 hours long while a day on Earth is 23.934 hours long. Continue the conversation on
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.
