the sun and the planets are attracted to each other by the force of gravity...... gravity is trying to pull the sun and the planets together into one big crash......
the planets are speeding around the sun..... their "speed" creates a centrifugal force that counter-balances the force of gravity so that they stay in orbit and do NOT crash into the sun.....
fill a small bucket (with a handle on it) about 1/4 full of water. hold the handle and let the bucket hang down to about your knee..... then swing the bucket in a circle over your head.....
if you keep the bucket moving in a circle, the water will stay in the bucket and not spill due to centrifugal force. if you stop swing the bucket when it is over your head, gravity will make you all wet.
now just imagine your head is the sun and the water in the bucket is Earth......
make sense?

gravity. The gravity of the sun keeps the planets orbitting it.

centrifugal force keeps us from falling in and gravity keeps us from moving away
