What force keeps the planets from flying out of the solar system?

Answer 1

Two answers . No. 1 :it's the force of gravity says Newton No. 2 :there is no force. The mass of the sun curves space-time. Each planet moves along what is, for it, the easiest path says Einstein Which one is right ? Well, Newton is right to a pretty close approximation, but Einstein is even closer. The orbit of Mercury is well predicted by Einstein's theory, but not by Newton's.

Answer 2

The force of gravity. Any mass will have gravity, the magnitude of which depends on the size of the mass. The earth and the moon attract each other, but at the same time their speeds relative to each other work in the opposite direction. These forces are balanced out like two people spinning while holding each others hands.

Answer 3

There is no force that prevents things crashing into each other. The fact that they do not crash into each other does not mean there is something preventing it.

Each planet is in its own stable orbit round the Sun, with the force of gravity pulling it towards the Sun, but that force is exactly balanced by an acceleration towards the Sun according to Newton's laws of motion.

The sideways speed of the planet means that the acceleration only makes the planet continuously curve towards the Sun without ever going much closer.

Answer 4

very large and powerful rubber bands hold them ie planets in place

Answer 5

Gravity and Inertia.

Answer 6

the gravity from the moon

Answer 7

Gravity.
