There is absolutely nothing that does not move. The sun is moving at an amazing velocity around the center of the Milky Way galaxy (~2.20×105 m/s), and the galaxy itself is moving relative to other galaxies. See related links.
==Alternate answer==
There is no absolute motion, we can only tell if something is moving and at what speed *relative* to another object.
For instance, lets say only one thing existed in the universe, a single particle. How could you tell how fast it was moving? Or if it was moving at all?You couldn't. But if another particle exists, and it moves towards or away from the first one, you can measure how fast it is going relative to the first particle. But for all you know both could be going a thousand miles an hour and one could be "gaining" on the other, there is no way to know for sure.
So if you're driving your car 50 miles per hour, that is not your absolute speed, it is your speed relative to the road. You are moving at thousands of feet per second on the earth relative to the sun, and much faster relative to the galaxy and faster yet relative to other galaxies.
So is the sun moving? Yes, *relative* to other objects. But there is no absolute motion.
