  1. 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. The planet orbits the Sun in 687 days and travels 9.55 AU in doing so, making the average orbital speed 24 km/s. The eccentricity is greater than that of every other planet except Mercury, and this causes a large difference betw… See more

    Changes in the orbit

    Mars is in the midst of a long-term increase in eccentricity. It reached a minimum of 0.079 about 19 millennia ago, and will … See more

    Oppositions

    Mars reaches opposition when there is a 180° difference between the geocentric longitudes of it and the Sun. At a time near opposition (within 8½ days) the Earth–Mars distance is as small as it will get during that 780-day … See more

    Close approaches to Earth

    Mars comes closer to Earth more than any other planet save Venus at its nearest—56 million km is the closest distance between Mars and Earth, whereas the closest Venus comes to Earth is 40 million km. Mars comes clos… See more

  1. 687 Earth days
    • According to 2 sources
    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.
    Because of Mars’s relatively elongated orbit, the distance between Mars and the Sun varies from 206.6 million to 249.2 million km (128.4 million to 154.8 million miles). Mars orbits the Sun once in 687 Earth days, which means that its year is nearly twice as long as Earth’s.

  7. Timekeeping on Mars - Wikipedia

    The length of time for Mars to complete one orbit around the Sun in respect to the stars, its sidereal year, is about 686.98 Earth solar days (≈ 1.88 Earth years), or 668.5991 sols. Because of the eccentricity of Mars' orbit, the seasons are not …
