  2. Synodic day - Wikipedia

    en.wikipedia.org/wiki/Synodic_day

    A synodic day (or synodic rotation period or solar day) is the period for a celestial object to rotate once in relation to the star it is orbiting, and is the basis of solar time. The synodic day is distinguished from the sidereal day , which is one complete rotation in relation to distant stars [ 1 ] and is the basis of sidereal time.

  3. Orbit of Venus - Wikipedia

    en.wikipedia.org/wiki/Orbit_of_Venus

    The distance between Venus and Earth varies from about 42 million km (at inferior conjunction) to about 258 million km (at superior conjunction). The average period between successive conjunctions of one type is 584 days – one synodic period of Venus. Five synodic periods of Venus is almost exactly 13 sidereal Venus years and 8 Earth years ...

  4. Transit of Venus - Wikipedia

    en.wikipedia.org/wiki/Transit_of_Venus

    During the Earth's 243 sidereal orbital periods, which total 88,757.3 days, Venus completes 395 sidereal orbital periods of 224.701 days each, which is equal to 88,756.9 Earth days. This period of time corresponds to 152 synodic periods of Venus. [2]

    On August 23, 2023, Venus retrograde and Mercury retrograde will join forces for a wild and crazy finale to summer. As you look at your calendar to lock in your last-minute summer plans, there are ...

  6. Venus - Wikipedia

    en.wikipedia.org/wiki/Venus

    It takes 224.7 Earth days for Venus to complete an orbit around the Sun, and a Venusian solar year is just under two Venusian days long. The orbits of Venus and Earth are the closest between any two Solar System planets, approaching each other in synodic periods of 1.6 years. Venus is the easiest destination to reach from Earth because of the ...

  7. Phases of Venus - Wikipedia

    en.wikipedia.org/wiki/Phases_of_Venus

    The orbit of Venus is 224.7 Earth days (7.4 avg. Earth months [30.4 days]). The phases of Venus result from the planet's orbit around the Sun inside the Earth's orbit giving the telescopic observer a sequence of progressive lighting similar in appearance to the Moon's phases. It presents a full image when it is on the opposite side of the Sun.

  8. Sidereal time - Wikipedia

    en.wikipedia.org/wiki/Sidereal_time

    Mercury's sidereal day is about two-thirds of its orbital period, so by the prograde formula its solar day lasts for two revolutions around the Sun – three times as long as its sidereal day. Venus rotates retrograde with a sidereal day lasting about 243.0 Earth days, or about 1.08 times its orbital period of 224.7 Earth days; hence by the ...
