Quick Answer: Which planet spins the fastest in order?

The solar system has eight planets, which orbit around the sun. Out of the eight planets, six rotate around their axis in the same direction besides revolving around the sun. Jupiter is the fastest spinning planet while Venus is the slowest.

What is the fastest spinning planet?

Jupiter is the fastest spinning planet in our Solar System rotating on average once in just under 10 hours. That is very fast especially considering how large Jupiter is. This means that Jupiter has the shortest days of all the planets in the Solar System.

What is the slowest rotating 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.

Which two planets spin most quickly?

Earth rotates once in 24 hours; whereas, Jupiter rotates more quickly, taking only about 10 hours. This means that Jupiter rotates about 2 1/2 times faster than the Earth.

Does Saturn spin fast?

Orbit and Rotation

Saturn has the second-shortest day in the solar system. One day on Saturn takes only 10.7 hours (the time it takes for Saturn to rotate or spin around once), and Saturn makes a complete orbit around the Sun (a year in Saturnian time) in about 29.4 Earth years (10,756 Earth days).

What determines how fast a planet spins?

The rotational speed is normally determined by the initial angular momentum when the planet formed, but may also be altered subsequently by large collisions (as for example the collision of the earth with another planet which gave us our moon).

Why does Uranus spin backwards?

Uranus was likely hit by a very large planetoid early in its history, causing it to rotate “on its side,” 90 degrees away from its orbital motion. Venus rotates backwards compared to the other planets, also likely due to an early asteroid hit which disturbed its original rotation.

What if Earth stopped spinning?

If the Earth were to stop spinning on its axis, gradually the oceans would migrate towards the poles from the equator. … You could travel around the Earth on the equator and stay entirely on dry land—ignoring the freezing cold on the night side, and the searing heat on the day side.

What planet is closest to the sun?

Mercury—the smallest planet in our solar system and closest to the Sun—is only slightly larger than Earth’s Moon. Mercury is the fastest planet, zipping around the Sun every 88 Earth days.

What causes a planet to spin?

Our planets have continued spinning because of inertia. In the vacuum of space, spinning objects maintain their momentum and direction — their spin — because no external forces have been applied to stop them. And so, the world — and the rest of the planets in our solar system — keeps spinning.

What planet spins on its side?

Like Venus, Uranus rotates in the opposite direction as most other planets. And unlike any other planet, Uranus rotates on its side.

How fast does Saturn spin in mph?

Saturn revolves or orbits around the Sun once every 29.4 Earth years, or once every 10,755.7 Earth days. Saturn travels at an average speed of 21,637 miles per hour or 34,821 kilometers per hour in its orbit around the Sun.

Why Jupiter spins 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.
