Pair with NGC 7818

NGC 7816 is listed as being in pair with the galaxy NGC 7818.[4][5] NGC 7818 is also listed as being a disturbed member of the pair.[4][6] However, due to the large difference in their recessional velocities, the two galaxies are not a true pair but an optical double.[4]

gollark: This what?
gollark: Hate WHAT?
gollark: I wrote this nice type signature:```rustfn solve(desired: Item, available: Vec<Item>, recipes: MultiMap<ItemType, Recipe>) -> (Vec<Recipe>, Vec<Item>)```
gollark: It'd probably be a bit more annoying, given constraints like "only X amount of items is available".
gollark: Which is apparently NP-hard, since someone managed to encode "SAT solving" or whatever in it.
