In the rebels' holographic simulation (a beautiful effect), the Death
Star is shown in a geostationary (well, endorstationary) orbit. It is
also shown as being only a few Death-Star-radii from the surface, and
certainly less than one Endor-radius.
There is a contradiction here. For the stationary orbit to be that
close, either the planet spins in only a few hours, or it has very light
gravity. The scenes on Endor's surface showed no evidence of either of
the above.
Possible fixes: even when only partially operational, the Death Star
could levitate; or maybe the shield generating station also provided
levitation until the Death Star's engines came on line. Or maybe the
planet did have very light gravity, but there was a humongous mascon
right under the shield station, providing "normal" gravity in the
immediate area. Except that you would expect a lake to collect...
