So if we're sticking 2-3 facilities on an asteroid*, how many on a planet the size of Pluto (~55 times the surface area)? How many on a planet the size of Earth (~500 times the surface area in land alone, ~1700 times if you include the seas)?


* Personally I wouldn't go for anything much smaller than 150km across, our asteroid belt has about 75 of that size that we know of, and an asteroid of that size gives a rough land area of 100,000/150,000 Km^2 per facility (for 3/2 facilities)
