With the case of the the moving planets, it's actually a giant Mover. If there are decorations then those are attached to Movers themselves. While I'm not looking at it specifically it's either a Mover with the Properties=>Movement=>Rotating and one of the axis is set to a number. Or it's a Mover with keyframes and there are 2 Dispatchers that bounce back and forth and constantly trigger each other (ie: DM-HyperSpace)
