How about a non-FE'er explanation using FE models?
The Universal Acceleration funnels back in around the edges of the disk and up to catch the sun and the moon and keep them at a static distance from the earth under the same Accelerative force.
Clearly, in a FE model, if you can get an object into this Universal Acceleration field, it would stay aloft on its own at a constant height from the earth's planar surface, much like the moon and the sun, and then it could maintain a circular orbital path above this surface, in the same fashion as the sun and the moon.
