  2. Venus - Wikipedia

    Because of the retrograde rotation, the length of a solar day on Venus is significantly shorter than the sidereal day, at 116.75 Earth days (making the Venusian solar day shorter than Mercury's 176 Earth days — the 116-day figure is close to the average number of days it takes Mercury to slip underneath the Earth in its orbit [the number of ...

  3. Sidereal time - Wikipedia

    en.wikipedia.org/wiki/Sidereal_time

    The March equinox itself precesses slowly westward relative to the fixed stars, completing one revolution in about 25,800 years, so the misnamed "sidereal" day ("sidereal" is derived from the Latin sidus meaning "star") is 0.0084 seconds shorter than the stellar day, Earth's actual period of rotation relative to the fixed stars.

  4. Terraforming of Venus - Wikipedia

    en.wikipedia.org/wiki/Terraforming_of_Venus

    A Venusian sidereal day thus lasts more than a Venusian year (243 versus 224.7 Earth days). However, the length of a solar day on Venus is significantly shorter than the sidereal day; to an observer on the surface of Venus, the time from one sunrise to the next would be 116.75 days. Therefore, the slow Venerian rotation rate would result in ...

    For example, Venus's year (sidereal period) is 225 days, and Earth's is 365 days. Thus Venus's synodic period , which gives the time between every two eastern greatest elongations, is 584 days; this also applies to the western counterparts.

  6. Orbital period - Wikipedia

    en.wikipedia.org/wiki/Orbital_period

    This is longer than the sidereal period of its orbit around Earth, which is 27.3 mean solar days, owing to the motion of Earth around the Sun. The draconitic period (also draconic period or nodal period ), is the time that elapses between two passages of the object through its ascending node , the point of its orbit where it crosses the ...
