Why does the planets always rotate?

Answer 1

Firstly you have to understand a few basic facts.

The gravitational pull of the moon causes a bulge in the waters on earth, this causes the tides.

The mass of the bulge of water also exerts gravitational pull on the moon.

And as the earth rotates it causes the bulge of water to move which pulls the moon towards it thus accelerating it.

Basically the moon is accelerating as a result of the rotation of the earth.

And contrary to what was written previously as an answer to this question the moon is not getting closer to the earth, the moon will not collide with earth.

Measurements by NASA have confirmed that the mean (average) distance between the earth and the moon is increasing by 3.8cm every year.

Answer 2

The planets are constantly accelerating because they are moving in a circular path. Acceleration is defined as a change in velocity. Velocity is a vector made up of a speed and a direction. While the speed of the planets may be constant, the direction they are moving is not. This is a change in velocity, which is acceleration.

Answer 3

Why does the planets always rotate? what is the temperataure of the planet mars?
hoe long in earth days does it take mars to rotate around the earth?
what is the size of the planet mars?
could a human survive on the planet mars?

Answer 4

Even the Moon is moving away from the Earth each year by approximately 1 inch. What keeps the planets in their alignment? Why aren't they either being drawn into the Sun or pushed away(like our moon to Earth)?

Answer 5

Planets rotate due to the conservation of angular momentum from their formation. Angular momentum is a property that describes the rotational aspect of an object and is preserved unless acted upon by an external torque. As planets formed from a spinning disk of gas and dust in the early solar system, they inherited this rotational motion and continue to spin today.
