Eight years
- 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.

Jan 22, 2023 · 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.
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]
Venus Phase Cycle, 1900-2050. Venus takes only 225 days to orbit the Sun. However, when she is viewed from Earth, her full synodic cycle (from inferior conjunction to inferior conjunction with the Sun) takes 584 days, or about 1.6 years.

Nov 8, 2024 · The Short Answer: Here is how long it takes each of the planets in our solar system to orbit around the Sun (in Earth days): Mercury: 88 days. Venus: 225 days. Earth: 365 days. Mars: 687 days. Jupiter: 4,333 days. Saturn: 10,759 days. Uranus: 30,687 days.
This simulation demonstrates the cycle of the phases of Venus. Click Start Animation. Note that and both venus and Earth now revolve around the Sun with their correct orbital speeds (described by what we call Kepler's 3rd Law today). Which planet moves faster (and can you explain why)?

Nov 21, 2016 · As Venus orbits the Sun, the phase of the planet appears to change (rather like those of the Moon). The phases of Venus and the idea of elongations are easier to understand if we use a picture. In Figure 1 an illustration showing the orbit of Venus as it moves around the Sun.
