Mars Facts - Science@NASA
As Mars orbits the Sun, it completes one rotation every 24.6 hours, which is very similar to one day on Earth (23.9 hours). Martian days are called sols – short for "solar day." A year on Mars lasts 669.6 sols, which is the same as 687 Earth days.
Orbit of Mars - Wikipedia
Mars has an orbit with a semimajor axis of 1.524 astronomical units (228 million km) (12.673 light minutes), and an eccentricity of 0.0934. [1][2] The planet orbits the Sun in 687 days [3] and travels 9.55 AU in doing so, [4] making the average orbital speed 24 km/s.
Orbit and Rotation of Mars - Planet Facts
Mars distance from the Sun is 230 million km and its orbital period is equal to 687 Earth days. For this planet, the solar day is only a bit longer than that of the Earth’s day which is 24 hours, 39 minutes and 35.244 seconds. An entire Martian year would equal 1.8809 in Earth years.

Mars - Wikipedia
Since the late 20th century, Mars has been explored by uncrewed spacecraft and rovers, with the first flyby by the Mariner 4 probe in 1965, the first orbit by the Mars 2 probe in 1971, and the first landing by the Viking 1 probe in 1976. As of 2023, there are at least 11 active probes orbiting Mars or on the Martian surface.

2 天之前 · Its axis of rotation is inclined to its orbital plane by about 25°, and, as for Earth, the tilt gives rise to seasons on Mars. The Martian year consists of 668.6 Martian solar days, called sols. Because of the elliptical orbit, southern summers are shorter (154 Martian days) and warmer than those in the north (178 Martian days).
