Do inner planets rotate quickly

Yes they move more quickly, and the orbital speed is proportional to the inverse square-root of the distance from the Sun. So a planet at a quarter the distance would have twice the speed.

That's "revolution" around the Sun,

but if the question really means "rotation", then it's about

the speed at which a planet spins on its axis.

The answer to that is Mercury and Venus spin very slowly. Earth and Mars spin fairly quickly.

Which inner planet rotates?

All of the planets rotate.


Why do the inner planets rotate on their axis's slower compared to that of the outer planets?

The inner planets rotate slower on their axis compared to the outer planets because they formed closer to the Sun where the gravitational interactions and tidal forces were stronger during the early stages of the solar system's formation. These forces acted to slow down the rotation rates of the inner planets over time. Additionally, the smaller mass and size of the inner planets also contribute to their slower rotation.


What do the inner planets do more quickly than the outer planets?

because of gravitational force of the earth is more in inner planet


How does the length of a day on the inner four contrast with the length of a day on the outer four?

The inner four terrestrial planets have shorter days compared to the outer four gas giants. This is because the inner planets rotate more quickly due to their smaller size and proximity to the sun, while the outer gas giants rotate more slowly because of their larger size and distance from the sun.


Why do the planets roate?

They rotate do to the gravitational pull of the sun... The rotate themselves due to their inner core rotating which is also caused by gravity


Why do the outer planets spin faster than the inner ones?

The outer planets are composed mostly of gases, which do not have a solid surface like the inner planets. This lack of solid surface allows the outer planets to rotate more quickly, as there is less resistance for their rotation. Additionally, the outer planets have more mass, which also contributes to their faster rotation.


What is the characteristics of the outer planets?

All outer planets have a gaseous atmosphere and are larger than planets the inner planets it also takes them longer to rotate the sun they are typically colder and have more moons.


What are some similarities of the inner and outer planets?

Inner and outer planets have some things that are in common but there mostly way different. For instants they both orbit the sun. On the other hand the outer planets are made mostly by gas, that's why they are called the gas giants. The inner planets are mostly made by rock and dust. The inner planets are called Terrestrial planets and the outer planets are called Jovian planets. The inner planets are closer to the sun, have more density, they have less moons, there about the size of Earth, and they rotate slowly. The outer planets (Jovian Planets) are farther from the sun, they have less density, they have more moons, they are large, about the size of Jupiter, they rotate rapidly, and they have more mass. These planets are alike because they both orbit the sun.


None of the inner planets have what?

none of the inner planets


Is jupitre a gassey planet?

Yes. Jupiter and so are the other outer planets are called "Gass Giants". Though they're massive, they can rotate faster than the inner planets.


When moving from the outer planets to the inner planets what can be said about their periods of revolution?

As planets move from outer to inner planets, their periods of revolution decrease. This is because the inner planets are closer to the Sun, so they have shorter orbital paths and complete their revolutions more quickly. Outer planets, being farther from the Sun, take longer to complete their journeys around it.


List inner planets and why they are inner planets?

The inner planets are Mercury, Venus, Earth, and Mars. They are "inner" because the are the first 4 planets from the Sun.
