Colombo is a lunar impact crater that lies on the strip of rough continental terrain between Mare Fecunditatis to the east and Mare Nectaris in the west. It is located to the south of the crater Goclenius, and northwest of Cook, and is named for the late 15th and early 16th century Italian explorer Christopher Columbus.

The rim of Colombo is circular, although slightly indented along the northwest where Colombo A intrudes slightly into the interior. The inner wall is asymmetrical, being much more narrow to the north and northwest and wider to the southeast. The rim is somewhat eroded, and several tiny craterlets lie along the inner wall to the southeast. The small satellite concentric crater Colombo B[1] lies across the south-southwestern rim.

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Colombo.

gollark: "Flat" would just be a "home" in a high-density/high-size thing.

gollark: You should probably have size and density things actually.

gollark: Okay, more: barn, farm, greenhouse, shed, museum, arena of some kind, city hall (or other governance building), embassy, post office, granary, bunker, missile launch facility, airport, taxi station, shipyard, and gym.

gollark: Okay then. Buildings which could exist: house, office, shop, mall, factory, mine, school, police station, SCP containment warehouse, regular warehouse, bus station, bus *stop* (sort of a building), underground train network stop, non-underground train network station, fire station, fire removal station, power plant, apiary, sewage treatment facility, garbage dump, garbage incinerator™, hospital, clinic (small hospital), plaza, park (sort of building), data center, hotel, prison, retirement home, theater, retirement home, restaurant, cafe, bowling alley, car wash, self-storage facility, seaport, car repair place, car dealership, bookshop, library, scientific laboratory, bank, substation, *nuclear* power plant, university, radio/TV/whatever transmitter, cell tower, [more coming].You should probably have a mechanic so you can have, say, apartment buildings composed of multiple "houses", but more generalized.
