Maybe...and please don't laugh...it could be Bespin!?!?
Because it just looks like a big gas-giant and Bespin looks almost the same if you watch ESB closely and there are little moons/planets or so near Bespin if you look close enough!!!
Okay, there are more than one of those planets in the SW-Universe...but who knows, right?????
Just a thought......
