Why do the planets go around the sun?

Answer 1

This is mainly because the sun has a much higher mass than any other object inside our solar system. The sun is so heavy that most other objects close to it start rotating around it. The same happens, on a miniature scale, with the Earth and the moon, where the moon rotates around the Earth because the Earth has the highest mass of any object close to the moon.

Answer 2

The sun is so large that it has gravity and pulls in nearby objects, making it hard to escape this gravitational pull.

2nd Answer:

Good answer except: All objects have gravity . . . you have gravity, I have gravity, the Moon has enough gravity to move Earth's oceans back and forth, causing the tides, and of course the Earth itself has a tremendously large force of gravity - this keeps us from floating off the Earth's surface into space.

The Sun's gravity is super-tremendously large, and can keep planets and comets orbiting from millions upon millions of miles away.

Keep in mind that with gravity, two or more objects attract each other. While the Earth pulls on the Sun, of course the Sun pulls back much more forcefully. Out of the 4 forces between particles, (Electrostatic, strong nuclear, weak nuclear, gravity) gravity is the only one with enough attraction to reach across really large distances.

Answer 3

The sun is much more massive than all the planets in the Solar System combined. Gravity pulls on pairs of objects equally toward each other. But because the sun is so massive, the pull doesn't affect its motion very much so the sun stays more or less at the center of the solar system while all the planets revolve around it.

Answer 4

The existence of large objects like planets or stars curve space and time. As the Earth goes around the sun it is in fact falling into the sun. The problem is that the sun and other planets are also moving. Gravity from the sun's previous location takes time to reach the Earth and planets such that the gravity from another location reaches the targets first. As the Earth and other planets reach a location where it might be moving in; the sun moves again, and other planets impart their gravity as well. The gravity of the sun becomes diluted throughout the heliosheath because of this weakening the effect of gravity even further.

Answer 5

Because it has been captured by the Sun's gravity, so it is condemned to travel round and round for ever. It is going fast enough so that it will never fall in, but its orbit changes very little as time goes by.

Answer 6

because if it did not move then it would all was be cold in one place and worm in a nother place ne the sun
