I can testify that kind of thing is random, skywalkerhogie.
One game, I had not one, not two, not three, but four Perfect (ie 16+) Planets within easy distance of my Home Planet (by easy I mean the beginner Colony Ship could just mosey along and grab them). Some with very useful Artifacts - Chimeric Biomass, Precursor Archive - as well. And they were in systems with other planets with the same or similarly useful goodies - either more Artifacts or heaps of one type of resource.
Next game, there were nought but crap as far as the eye could see.
