I need four individual solar systems built, and if possible, put into one simulation. Each solar system must have a minimum of one habitable planet, no more than five. At least six planets each solar system. Only one of the habitable planets can be "earth-like." There also needs to be an asteroid field surrounding and in between the four solar systems. I'm really not sure how deep or shallow this simulator goes, but I need as much detail as possible. Let me know if you can help! It'd be much appreciated.
Do you want them to be a four-star system, (not five-star ) or systems spaced FAR AWAY. (like 2 lightyears.)
He said individual, so I'm assuming they are some light years from each other.
Anyways, as for constructing the systems, you can use Bodes Law to determine the position of the planets as described
here, theres more resources that can be useful to you as well, including a site where you can generate random planets. Also, if you don't have any specific star types in mind, you can use
this thread to generate random stars.
As for asteroid belts, go to the add tool, click the body you want to put rings around and click any of the ring types (you can change them in the side box). For notable asteroid colonies, you can just plop down any asteroid bodies in the area.
