How are we putting satellites in space if we can’t even solve the three body problem?

In physics, the three body problem is the problem of taking the initial positions and velocities of three masses and solving for their subsequent motion according to Newton’s laws of motion. As far as I know this has never been solved for the motions of the earth, sun and moon. Even with supercomputers, we can not do it. If we can’t even mathematically model gravity for 3 cosmic bodies out of an infinite number, how are we sending satellites into orbit?
