  1. 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 of equal length.

  2. Nov 20, 2023 · So expressed in Earth time, on Mars each solar hour is 1 hour 1 minute 39 seconds (1/24 of a sol) long, each solar minute is 61.65 seconds long, and each solar second is 1.0275 seconds long. This ...

    This system would preserve the length of terrestrial hours, minutes, and seconds, but add an extra partial hour after midnight, and has made fictional appearances in Kim Stanley Robinson’s Mars trilogy,as well as Philip K. Dick’s Martian Time-Slip. Despite the practicalities of preserving conventions familiar to Earth residents, the partial hour pr...

    The proposal of decimal time seeks to use the settlement of Mars as an opportunity to replace Earth’s somewhat unwieldy base-24 and base-60 time system with a sleeker one utilizing units of 10. Earth seconds could provide the basis for such a system: terrestrial time already uses milliseconds and microseconds, and this convention could be extended ...

    The system currently in place for telling time on Mars simply divides the solar day by 24 hours to yield familiar hours, minutes, and seconds, each 1.0275 times longer than their terrestrial equivalents. This method has the practical benefits of remaining similar to Earth time without necessitating the inconveniences of an additional partial hour, ...

    As mentioned above, comparing the occurrence of sunrise and moonrises at local time to their expected occurrences at the prime meridian provides an accurate method to assess longitude. But where does one define the prime meridian on an extraterrestrial planet? On Mars, the definition of longitude 0° was originally set in 1877 based on the region Si...

  4. A day on Mars, also known as a “sol,” is slightly longer than a day on Earth. According to NASA, the average duration of a Martian day is 24 hours, 39 minutes, and 35.244 seconds. This is just over 2% longer than a day on Earth. The length of a day on Mars is determined by its rotation on its axis. The sidereal rotational period of Mars is ...
