Earth rotates once in 24 hours; Jupiter once in about 9.5 hours. The surface of Earth at the equator is rotating at about 1000 miles per hour, while Jupiter's equatorial cloud-tops are moving nearly 28,000 miles per hour.Earth rotates once in 24 hours; Jupiter once in about 9.5 hours.

How Fast Is Jupiter spinning?
Why is Jupiter spinning so fast?
When Jupiter formed, it accreted its atmosphere (over 95% of the planet's total mass!) from the hydrogen and helium gas in the protoplanetary disk surrounding our Sun. As Jupiter ate up this gas mass, it must have begun to spin faster as it also ate up the gas's angular momentum.
What is the fastest rotating planet?
Exoplanet Beta Pictoris b is the fastest-spinning known planet. At between 8 million and 20 million years old, the Beta Pictoris system, 63.4 light-years away, is still in its formative stage. Young planets are still accreting as planetesimals collide in the debris disk that surrounds the star.
Which two planets spin most quickly?
Jupiter Jupiter is the fastest spinning planet while Venus is the slowest.
What is the slowest spinning planet?
Venus What is the Slowest Planet. Venus, which is floating higher each evening in twilight, low in the west, is the slowest-spinning body in the known universe. If you walked along a bike path that circles its equator, you'd only need to go four miles an hour to keep night from ever falling on Venus.
Does Mars spin faster than Earth?
Keeping time in Mars will be different as compared to Earth because the two planets take different amounts of time to orbit the Sun. And even though they both rotate on their axis, they both differ regarding the speed of the rotation. Mars rotates at a rate 2.7 percent slower than Earth.
Why is Pluto no longer a planet?
The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”
Which is the deadliest planet?
0.015% 0.007% 3.5% 64% Page 2 Venus is the most dangerous planet in the solar system: its surface is at 393°C, hot enough to melt lead. It's even hotter than the planet Mercury, which is closest to the Sun. Venus' atmosphere is acidic and thick.
How fast does Mars rotate?
Orbit and Rotation As Mars orbits the Sun, it completes one rotation every 24.6 hours, which is very similar to one day on Earth (23.9 hours).
