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
Martian days (one rotation) are slightly longer than Earth's, lasting about 24.66 Earth hours. As it orbits further from the Sun, its year (one revolution around the Sun) â¦ takes about 687 Earth days. So the Martian year consists of 668.6 Martian days. A Martian day is 39.5 minutes longer than an Earth day. But Mars' circumference is just over half of Earth's, so its spin velocity is also about half, just 868 km/hr compared to Earth's 1674 km/hr at the Equator.
