In the attachment below I've used xpresso with radius, speed, direction and start offset. There are many ways to do what you want - my way isn't the simplest, however its always good to know of another technique. If you put the userdata in the xpresso node instead you could put this in your content browser as a preset to drag onto any object. I just updated the c4d file - so now you can put it on any object or in your content browser. The userdata is on the xpresso tag. Add a parent null to reposition the orbit.
