It took me a while to figure out, but the camera centers around the white ball. If you use the arrows you are controlling the white ball, not the camera. Spacebar seems to make it go "up".

Ok whoa, this just got way cooler. Hold the left and right arrows alternately for a bit each side, you can build up a pretty big orbit..

Thanks, the low-poly planet models was created by others but they are really cool. The controls can be frustrating because I use velocity for the movement and it is connected to the ball not the camera.
