NGC 358

NGC 358 is a very small open cluster of four stars in the constellation of Cassiopeia. It was originally thought to be an unrelated Asterism, but two of the members were found to have a similar distance of roughly 1700 light years, although the other two do not have well-constrained distances, so its exact nature is uncertain.

gollark: Is Macron just SUBLEQ now?
gollark: Well, the matrix way lets you get fib(n) in O(log n) time, thus good.
gollark: It has 128-bit decimal floats with each component as quaternary posits, grouped into pairs to form complex numbers in all circumstances.
