I don't think you'll have all that much success using it as a vending machine. The Hessians definitely don't get as much pleasures out of cardimine as....Other allies of the Outcasts.

Nope, notice the rings around it. Compare with the Ross Planetoid in Cambridge. Its probably what's left of a small moon type thingamobob that got most of it sucked into the jumphole when it formed- the leftovers became the little rock and the rings floating around it. Just my theory, but it seems logical. (also explains the heavy asteroid field around the other side of the JH)
I think a couple rocks are hand-placed in small exclusion zones, like the ones sheltering the wrecks in the Tau-31 minefields, the aforementioned donut rock and rock sheltering the Tau-37 wreck. There's a few other oddball ones too, but I can't remember all of them.
