Why do the planets all stay in orbit around the sun and not drift off into empty spaces?

Answer 1

Gravity and Inertia. Gravity pulls the planets toward the sun, but inertia pulls it away. They keep it evenly balanced. angular velocity is balanced (mostly) by gravity.

Answer2:

The planets stay in orbit because the centripetal force of gravity vp/r is balanced by the centrifugal force cp/r cos(P). the centrifugal force is the divergence of the "Dark Energy" cmV =cP.

The real gravity energy is w = -mGM/r + cmV = -vp + cP where -vp is the potential scalar energy and cP is the vector energy, the so-called "Dark Energy". The vector energy is the force balancing the gravitational centripetal force. vp/r = cp/r cos(P) thus v/c = cos(P). This is the red shift and explains what the red shift is.

The Dark Energy is the vector energy associated with the Momentum mV. Dark Energy creates the orbit from : 0 = cdP/dr + muR/r3..

Answer 2

By the force of gravity, which pulls objects together with a force proportional to the masses of the objects involved. In the case of the planets the force of gravity pulling them towards the sun is exactly counterbalanced by the centripetal force which is trying to throw them off into space.

Answer 3

There are two factors; the tangential velocity, and the gravity. The planets have a tangential velocity, they are speeding along sideways relative to the sun. If there was no gravity, this velocity would take the planets away from the sun, but the sun has a huge gravitational force which counteracts this effect. The suns gravitational force is constantly attracting the planets in, against this tangential velocity. If the planets were to slow down, then they would eventually spiral into the sun, but in space there is no drag, so the planets maintain their speed and their orbits.

Answer 4

The combined effect of gravity and angular momentum keeps planets in orbit. Without gravity they would just fly away into space, and without angular momentum they would just fall into the sun, but the combined effect of both of these results in an orbit.

Answer 5

The sun is enormous, out massing all the planets combined by a factor of at least a thousand. The solar gravity keeps the planets gravitationally bound to their orbits.

Answer 6

The gravity of the Sun deflects the otherwise straight line trajectory of the planets due to their momentum.

Answer 7

The sun's gravity keeps them in orbit.
