What is gravity

Gravity works like a magnet it pulls objects together. and the more matter there is more gravity.And if there's more gravity it pulls lots.And if the gravity is less,the things will nearly float.The sun has lots and lots of gravity.So the gravity pulls the earth and the other planets.That is how the eight planets are made.If there was no gravity there we'll be no eight planets.Well, Pluto was a planet but scientists found many other planets like plouto so scientists said the plouto and other planets like plouto are not in the 9 planets so it turned 8 planets.And black hole has lot of gravity so once you got there you can't get out
