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]
Earth's nearness to Venus is a matter of perspective. The planet is nearly as big around as Earth. Its diameter at its equator is about 7,521 miles (12,104 kilometers), versus 7,926 miles (12,756 kilometers) for Earth. From Earth, Venus is the brightest object in the night sky after our own Moon.
Nov 8, 2024 · 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 ...
Jan 22, 2023 · Mar 25, 2017: is in Pisces; Venus passes 8 degrees north of the sun; distance from us 0.28 AU (astronomical units, aka sun-Earth distances); diameter of Venus’ (mostly dark) disk 60″ .
One day on Venus – the time it takes the planet to complete a full rotation on its axis – is equal to 243 days on Earth. That is actually slower than the time it takes for Venus to complete one orbit around the Sun, which takes 225 Earth days. On Venus, as on Mercury, a year is actually shorter than a day!
The orbits of both Earth and venus are shown as they would have been envisioned back in the time of Copernicus – in circular orbits in the same plane centered upon the Sun. Earth's orbit has a radius of 1 AU and distances in the solar system were measured in terms of this unit, even though it wasn't understood how big that distance was in terms of other units (like miles).

The most recent Transit of Venus occured on 5-6 June 2012. No further transits will be visible until 2117. In astronomy, a 'transit' occurs when a smaller body passes in front of a larger one. A 'Transit of Venus' happens when Venus is seen in silhouette against the bright face of the Sun.
