What force holds a planet in orbit around the sun?

Answer 1

Gravitation. The phenomenon by which two masses attract each other with a force proportional to the product of their masses and inversely proportional to the square of the distance between them.

Answer 2

Acceleration due to gravity.

Because both Earth and Sun have gravity, they are attracted to each other. Hence they should join together, but they don't.

In Newton's Laws of Universal Dynamics, a body will remain stationary or in uniform motion , unless acted up by a force. (NB Uniform motion means in a straight line at constant speed).

So the Earth moves in a stright line, but the Sun;s gravitational acceleration acts upon it. These two forces come into balance so the Earth remains in orbit about the Sun, As do all the other objects in the Solar system.

Remember the Earth, with repect to the Sun , is acclelerating through space.

Accleration comes about throug a change of veloicty, and velocity is speed in a given direction. Since our direction is constantly changing ( not a straight line, but orbiting) we have a change of velocity hance acceleration about the Sun.

Answer 3

Wherever you see things in space that pretty much stay together and

don't go flying off on their own, it's gravity holding them together.

That goes for the actual material that stars and planets are made of, and

for their families of moons, asteroid belts, rings, solar systems, galaxies, and

clusters of galaxies.
