The Earth's gravity is trying to pull the Moon towards the Earth. However, the Moon has inertia. It is trying to move in a straight line. If the Moon had no "sideways" velocity it would fall onto the Earth.
In fact the Earth's gravity is needed just to bend the direction of the Moon's
path and make the Moon orbit the Earth instead of flying off into space.
This becomes clear if you do the mathematics, but that's the basic idea.
The gravity wants to pull orbiting objects in, but the inertia wants to keep them moving straight so the gravity just makes it go around.
That would be gravity and inertia.
Inertia keeps the planets revolving around the sun instead of just running into the sun. Since gravity pulls masses together, without inertia, all the planets would be pulled into the sun.

It keeps the solar system together because without it we would be floating around. :)
Intertia and Gravity
That would be gravity and inertia.

Yes, It holds the whole solar system together.
There is no gravity in space, everything is weightless.
Gravity.
Gravity
It holds the Solar System together?
If there were no gravity, you would not have a Solar System. It is the force of gravity that attracts the various members together and forms a system.

With gravity and inertia. If you dont know what those look them up in a scientific dictionary.
