Stars and planets form in the collapse of huge clouds of interstellar gas and dust. The material in these clouds is in constant motion, and the clouds themselves are in motion, orbiting in the aggregate gravity of the galaxy. As a result of this movement, the cloud will most likely have some slight rotation as seen from a point near its center. This rotation can be described as angular momentum, a conserved measure of its motion that cannot change. Conservation of angular momentum explains why an ice skater spins more rapidly as she pulls her arms in. As her arms come closer to her axis of rotation, her speed increases and her angular momentum remains the same. Similarly, her rotation slows when she extends her arms at the conclusion of the spin.

In our solar system, the giant gas planets (Jupiter, Saturn, Uranus, and Neptune) spin more rapidly on their axes than the inner planets do and possess most of the system's angular momentum. The sun itself rotates slowly, only once a month. The planets all revolve around the sun in the same direction and in virtually the same plane. In addition, they all rotate in the same general direction, with the exceptions of Venus and Uranus. These differences are believed to stem from collisions that occurred late in the planets' formation. (A similar collision is believed to have led to the formation of our moon.)

Do all planets turn?

All planets turn on their axis. This is called the planet's rotation; one complete rotation is equal to one day on that planet.

Unless they turn into meteorites, and collide with the planets, pretty much not at all.

What are the differences between the eight planets and the sun?

The sun is made up of gas and the planets turn around it, whereas the planets are made up of what we find in the ground. Also, the sun is ALOT bigger and hotter than the planets.

It will turn into a Red Giant and then its corona expands and disintegrates all of the Rocky Planets.


Why are planets closest to the sun largely devoided of lighter elements?

The lighter elements turn to gas at a lower temperature and because of their lack of atmosphere are released from the planets out into space
