How to rotate a huge group object?

I encountered some problems (Graphics 2.0) as I wanted to rotate a huge group object with some child objects in it and I hope someone already has a solution on how this can be done right…

I have a small cloud image for a game screen. At the bottom of the screen you can see the top of a circle image. Now I want to rotate the cloud around the center of the huge circle image. The circle image top can be seen but the most part of the circle is off the screen. How can I rotate a group containing the cloud image around the center of the circle image?

Here is a sketch:

Any help welcome!

Thank you!

Hi.  Please take a look at this: https://github.com/roaminggamer/RG_FreeStuff/raw/master/AskEd/2014/06/rotatingWorldNoPhysics.zip

It may help.  However, this won’t help much if you need physical bodies to rotate about this ‘planet’.  That requires a very different approach.
