   • Rotation and revolution. Years on other planets are measured using Earth’s tropical year, which lasts about 365 solar days; one solar day is the time it takes our planet to spin, or rotate, once fully on its axis, as measured by the Sun’s position over a given point.
   • Laws of motion. Kepler’s third law of motion explains that the time it takes a planet to complete a revolution is related to its distance from our star.
   • Mercury. Mercury spins on its axis very slowly and completes one rotation every 59 Earth days. However, its orbit around the Sun is speedy compared to other planets.
   • Venus. The hottest planet in the solar system takes about 225 Earth days to complete one rotation around the Sun. Venus spins very slowly and appears to rotate retrograde, or in a clockwise direction – opposite from most planets, which rotate counterclockwise, or prograde, in the same direction as they move through their orbits.

   Oct 24, 2024 · It takes Venus 225 days to orbit the sun, which isn’t too much shorter than Earth’s 365 days. Mars is the outermost of the rocky planets, and so it takes the longest amount of time to orbit the sun in the inner solar system.

   Nov 8, 2024 · On Mercury a day lasts 1,408 hours, and on Venus it lasts 5,832 hours. On Earth and Mars it’s very similar. Earth takes 24 hours to complete one spin, and Mars takes 25 hours. The gas giants rotate really fast. Jupiter takes just 10 hours to complete one rotation.

   How long is a year on Mars?

   • One year on Mars equals 687 Earth days or 1.88 Earth years. On Mars, solar days are called sols, and one year is also 669.6 sols. Mars’ rotation is similar to Earth’s, and it completes one rotation every 24.6 hours. Related: What time is it on Mars? Jupiter, as imaged by the Hubble Space Telescope.

   How long is a year on Venus?

   • Basically, one part of the year is as hellishly hot, or horribly cold, as any other. The second closest planet to our Sun, Venus completes a single orbit once ever 224.7 days. This means that a single year on Venus works out to about 0.6152 Earth years. But, once again, things are complicated by the fact that Venus has an unusual rotation period.

   How long does it take Venus to orbit the Sun?

   • It takes Venus 225 days to orbit the sun, which isn’t too much shorter than Earth’s 365 days. Mars is the outermost of the rocky planets, and so it takes the longest amount of time to orbit the sun in the inner solar system. It takes Mars 687 days to orbit the sun, nearly twice as long as Earth’s year.

   How long does it take to orbit Mars?

   • Basically, Mars takes the equivalent of 687 (Earth) days to complete a single orbit around the Sun, which works out to to 1.8809 Earth years, or 1 year, 320 days, and 18.2 hours. On the other hand, Mars has a rotation period that is very similar to Earth’s – 24 hours, 39 minutes, and 35.244 seconds.
