   How long is a day on Venus? A planet's day is the time it takes the planet to rotate or spin once on its axis. Venus rotates much more slowly than Earth does, so a day on Venus is much longer than a day on Earth. A day on Venus lasts for 243 Earth days or 5,832 hours! A day on Earth is 23.943 hours. Venus also rotates backwards compared to the ...

   How long does it take Venus to spin?

   • On Earth, this “precession” takes about 26,000 years to cycle around once. Venus needs a little longer: about 29,000 years. With these exacting measurements of how Venus spins, the team calculated that the planet’s core is about 3,500 kilometers across — quite similar to Earth — though they cannot yet deduce whether it’s liquid or solid.

   How often does the sun rise on Venus?

   • But on Venus, the Sun rises every 117 Earth days. That means the Sun rises two times during each year on Venus, even though it is still the same day on Venus! And because Venus rotates backwards, the Sun rises in the west and sets in the east. Just like Mercury, Venus doesn't have any moons. Venus is the hottest planet in our solar system.

   Does a day last longer than a year on Venus?

   • It also means that if you could stand on the surface of Venus, the Sun would rise in the west and set in the east. From all this, one might assume that a single day lasts longer than a year on Venus. But again, the distinction between a sidereal and solar days means that this is not true.
