I've rated the torpedo firepower as zero because although the ship does have missiles, these probably don't really count as effective weapons by the standards of Star Trek, in much the same way that the first generation of muzzle loading rifles would pose pretty much zero threat to a modern army. Any ship should be able to completely avoid a chemically fuelled missile even on thrusters, let alone impulse drive, while a hand phaser should pack more than enough punch to deal with them. Incidentally it's never established what kind of warheads the missiles carry, but a nuclear device of some sort seems probable.
The overall strength index of 7 for the asteroid probably shouldn't be taken too seriously - the strength system doesn't work too well with ships that have little or anything in most categories and then one or two biggish numbers.
Although it's never made clear just how much space there is between the inner core and the outer shell, this cannot be all that great a distance. One of the residents of Yonada recalls an occasion when he was able to climb a mountain and touch the outer shell - hence the rather bizarre episode title. This would indicate that it's no more than a few kilometres at most, probably only one or two. It also proves that the mountains of the core reach to within touching distance of the outer shell. Indeed, it seems very likely to me that the so-called 'mountains' are in fact disguised columns which are there precisely to hold the core in place with respect to the shell.
The notes are pretty much a description of the episode. I've skipped the whole McCoy plotline because it didn't really tie in with the capabilities of the asteroid itself all that much.
Flushed with the success of the Defender and Gage classes, I tried to mock up a size comparison image for this. Suffice to say it didn't work out too well.... ;-)
