Gravity is the attraction between any two masses: F = G · m₁·m₂ / r² — stronger with more mass, weaker with the square of the distance. Here are just two bodies. The arrows show the pull each exerts on the other: exactly equal and opposite (Newton’s 3rd law), about 3.5 × 10²² newtons.
This page is a really great way to learn more about gravity and how it affects our solar system.
The use of interactive and animated web pages for learning resources seems to be growing steadily, I've seen a lot recently and presume as they get easier to make - will continue to do so.
