A day on Venus-the time it takes for the planet to complete one full rotation on its axis-is about 243 Earth days long, or approximately 5,832 hours
. This rotation is very slow compared to Earth’s 24-hour day and is in the opposite direction to most planets, known as retrograde rotation, meaning the Sun would appear to rise in the west and set in the east on Venus
. Interestingly, a Venusian day is longer than its year, which lasts about 225 Earth days
. The length of a day on Venus is not constant; it varies slightly by up to about 20 minutes due to interactions between the planet’s dense atmosphere and its surface features
. In summary:
- Venus’ day length: ~243 Earth days (about 5,832 hours)
- Venus’ year length: ~225 Earth days
- Rotation direction: retrograde (opposite to Earth)
- Day length varies slightly over time due to atmospheric effects
This slow and retrograde rotation, combined with a thick atmosphere, contributes to Venus’ extreme surface conditions
