How Long is a Day on Venus?

Article Updated: 24 Dec , 2015

Venus takes 224.65 days to complete each orbit. This is a little less than a year on Earth. But instead of a similar rotational period to Earth’s 24 hours, Venus takes 243 days to rotate once.

In other words, a day on Venus is longer than a year. This is the longest day in the entire Solar System. Even stranger, Venus rotates backwards compared to the other planets in the Solar System.

If you could stand on the surface of Venus, the Sun would appear to rise in the West and then set in the East.

    Venus does NOT “orbit backwards”. It orbits the Sun in the same direction as all the other planets, dwarf planets, and asteroids.

  2. justme says:

    it rotate backwards around its own axes but orbits the sun same direction as all other planets. (not sure though)

  3. Daniel says:

    justme is correct.

    What is often forgotten when talking about how long a day is on Venus, is that because Venus rotates slowly in a retrograde fashion and orbits conventionally, it is actually ~117 days between sunrises.

    how long is the day!!!

  5. Tori says:

    I still do not understand how long the day is. If it rotates backwards but orbits right the how long is the day?
