What prevents the sun from pulling the planets into it?
The orbital velocity (the speed of the planets' orbit) of the planets.

The planets' stable orbits around the Sun are maintained by their momentum and the balance between their tangential velocity (which keeps them from falling into it) and their gravitational attraction towards the Sun.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
