Distance estimates
A distance of (13 ± 2 Mpc) for NGC 4523 was derived from using yellow supergiants in the galaxy as standard candles.[6]
gollark: Go rule 11 yourself.
gollark: There was a bug in my version of `ringAt`, and with that fixed it's a bit better.
gollark: Somehow?
gollark: I might need to tweak the brightness.
gollark: It works! Roughly correctly!
