Gravitational Forces in our Solar System

Gravitational forces are always attractive. There is a gravitational force between any two masses, but it is very small except when one or both of the objects have large mass. 

Gravitational forces are best recognized in our solar system where objects like our Sun, the Earth, and other planets are VERY massive.
