Fastest day in the solar system

Which planet has the fastest rotation?

Farther out, the rest of the planets are more similar in rotation. A day on Mars lasts 25 hours, Saturn 11 hours, Uranus 17 hours, and Neptune 16 hours. But Jupiter is the fastest of them all, with its equator spinning at a rapid 43,000 kilometers per hour (28,000 miles per hour), about 28 times faster than Earth.

Which rocky planet spins the fastest?

Interestingly, the Earth actually spins the fastest among the rocky planets, completing one rotation every 24-hours. That translates to a rotational velocity of 1,574 kilometres per hour. Mars is the second fastest, and its rotational velocity and length of day are quite similar to Earth’s.

Which planet has the shortest day in the Solar System?

Jupiter has the shortest day in the solar system. One day on Jupiter takes only about 10 hours (the time it takes for Jupiter to rotate or spin around once), and Jupiter makes a complete orbit around the Sun (a year in Jovian time) in about 12 Earth years (4,333 Earth days).

Which planet has the fastest wind speed?

However, the planet’s rotational spin is not the only factor for wind speed, meaning that although Jupiter is the fastest spinning planet, it does not break the record for the fastest winds, which is Neptune at more than 1,200 miles per hour (2,000 km/h) in its upper atmosphere. The speed of a planet’s spin helps to shape the surface.

Which planet has the longest sidereal day?

Venus also has the slowest rotation of any planet in the solar system, and thus it has the longest measured sidereal day of any other planet. Venus rotates so slowly that it takes longer for Venus to rotate once about its axis than it does to orbit the sun. It takes Venus 225 days to orbit the sun, and 243 days to rotate once about its axis.

How long does a day last on other planets?

We can write a paragraph about how long days last on other planets. 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.
