   The complete cycle, however, new to full, takes 584 days, while our Moon takes just a month. And it was this perspective, the phases of Venus first observed by Galileo through his telescope, that provided the key scientific proof for the Copernican heliocentric nature of the solar system.

   The full cycle from new to full to new again takes 584 days (the time it takes Venus to overtake the Earth in its orbit). Venus (like the Moon) has 4 primary phases of 146 days each. The planet also changes in apparent size from 9.9 arc seconds at full (superior conjunction) up to a maximum of 68 arc seconds at new (inferior conjunction). [1]

   One more trick of perspective: how Venus looks through binoculars or a telescope. Keep watch over many months, and you’ll notice that Venus has phases, just like our Moon – full, half, quarter, etc. The complete cycle, however, new to full, takes 584 days, while our Moon takes just a month.

   Oct 31, 2023 · How Long Does Venus Take to Go Around the Sun? Often referred to as Earth’s Twin, the two planets are not that alike really but they are close neighbors. Venus however is closer to the Sun than our own planet and as a result has a shorter orbital period. It takes Venus roughly 225 Earth days to make an orbit of the Sun.

   How long does it take Venus to orbit the Sun?

   • It takes Venus roughly 225 Earth days to make an orbit of the Sun. A year on Venus then lasts 225 Earth days, roughly 140 days less than our own planet. Venus has a dense toxic atmosphere which is extremely heavy in carbon dioxide and is actually deemed the thickest found on all of our solar system’s rocky planets.

   How long does it take to reach Venus from Earth?

   • Our twin Venus is relatively close to Earth but it still takes a reasonably long time to travel in a spacecraft. The fastest we have reached Venus from Earth is 109 days and the longest it has ever taken was 198 days. The truth is the exact time varies on a number of factors such as where the two planets are in their respective orbits.

   What is the 8-year cycle of Venus?

   • After eight years, it returns to the same place in our sky on about the same date. This is known as the eight-year cycle of Venus, and stems from the fact that 13 Venusian orbits (13 x 224.8 days) very nearly equals eight Earth years. As a matter of fact, the cycle was known to, and of great interest to, ancient peoples such as the Maya.

   How long does it take to see the Sun on Venus?

   • For another, because of the planet's extremely slow rotation, sunrise to sunset would take 117 Earth days. And by the way, the Sun would rise in the west and set in the east, because Venus spins backward compared to Earth. While you’re waiting, don’t expect any seasonal relief from the unrelenting temperatures.
