I believe this doesn't work for motion paths. What you could do is to use expressions. Put your satellite planet where ever you want but place it's pivot in the center of the "host" planet. Then write expression to the planets y rotation. Quick example: Code: int $revsPerAnim = 1; int $animeLength = 300; yourSatellitePlanet.rotateY = frame * ($revsPerAnim * 360)/$animLength;
