@sreki have the scale in km and already did everything you told me to, i've created the nulls objects, placed them in the center, put the planets at place as well but i'm having a hard time to insert the data in xpresso (sorry i'm a beginner in C4D and i'm really challenging myself, spent the whole afternoon trying to get it done haha), could you help me out on this? here's the file
