Cannon (crater)

Cannon is a lunar impact crater that is located near the east-northeastern limb of the Moon's near side. It lies just to the northwest of the Mare Marginis, and south-southeast of the crater Plutarch. Farther to the east-northeast is Hubble.

This is a worn and eroded formation with an interior floor that has been resurfaced by lava. A small crater overlies the north rim, which forms a notch in the side. Tiny craters also lie across the rim northeast and at the southern edge. The interior is level and nearly featureless, with only a few tiny scattered craterlets to mark the surface. This floor has the same albedo as the surrounding terrain.

The crater is named after Annie Jump Cannon, an astronomer who classified 300,000 stellar bodies.

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 Cannon.

gollark: In any case, if you have a planned system and some new need comes up... what do you do, spend weeks updating the models and rerunning them? That is not really quick enough.
gollark: If you want to factor in each individual location's needs in some giant model, you'll run into issues like:- people lying- it would be horrifically complex
gollark: Information flow: imagine some farmer, due to some detail of their climate/environment, needs extra wood or something. But the central planning models just say "each farmer needs 100 units of wood for farming 10 units of pig"; what are they meant to do?
gollark: The incentives problems: central planners aren't really as affected by how well they do their jobs as, say, someone managing a firm, and you probably lack a way to motivate people "on the ground" as it were.
gollark: What, so you just want us to be stuck at one standard of living forever? No. Technology advances and space mining will... probably eventually happen.
