Most systems contain only barren, rocky planetoids (or very similar). This is a bit of a let-down if you're planning your holidays in an Alliance system, and you end up on one of these. The outdoor worlds tend to be more popular with travellers and have the most things to do on them as you might expect. However, don't discount all the barren rocky planetoids - to make up for the lack of anything else, some of them do have some pretty inventive nightlife.
