Why do outer planets move slower than the inner?

Gravity is stronger nearer the sun. Planets that are closer to the sun then need to have higher speeds in order to balance the higher pull of gravity. For the outer planets they have further to go and a slower speed so their orbital periods are much longer than that of the earth.

Do inner or outer planets have slower rotations?

Compared to the outer planets, the inner planets are small. They have shorter orbits around the Sun and they spin more slowly. Venus spins backward and spins the slowest of all the planets. All of the inner planets were geologically active at one time.

Why do the outer planets take longer to orbit?

Outer planets take longer to orbit than inner planets because of the greater distance they need to cover. They also are further from the sun weakening the power of the suns gravitational pull which causes then to orbit slower.

Which planet is the fastest revolving planet and why?

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.

Which inner planet has the fastest revolution?

But Mercury is the fastest planet, zipping around the Sun every 88 Earth days.

Why are the inner planets closer together than the outer planets?

The inner planets are closer to the Sun and are smaller and rockier. The outer planets are further away, larger and made up mostly of gas.

Do inner planets have fast rotations?

The Sun’s gravity holds the inner planets tightly as they revolve around the Sun. The orbits of Mercury, Venus, Earth, and Mars revolve faster than the outer planets because they have less distance to travel. Mercury and Venus rotate on their axis slower than any of the other planets.

Do the planets orbit at the same speed?

No. Orbital speed is determined by the mass of the object you are orbiting and your distance from it. All of the planets are orbiting the sun, so the mass is the same, but the distance is different. The further away they are, the slower they go.

What are the distances between each of the inner planets?

If you look at the orbits of the inner planets, i.e. Mercury, Venus, Earth, and Mars, they are not too far from each other, with mean orbital radii ranging from 0.39 AU for mercury through 1.52 AU for Mars. Then there is a large gap from Mars to the nearest outer planet, Jupiter.

Why are larger planets farther from the Sun?

In the areas closer to the Sun, it’s too warm for the lighter gases to condense there, and so the larger gas and ice giants tended to form further from the Sun.

What planet rotates faster than the Earth?

Jupiter
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.
