minus-square@AllerolinkEnglish5•16 days agoThey normally use parallax-seconds, i.e. parsecs, for long distance objects.
minus-square@m0darn@lemmy.calinkfedilinkEnglish2•15 days agoI think you need to be more specific than ‘long distance’, yes they use parsecs for ‘long distances’ but I believe only for intra-galactic objects. I think other galaxies are too distant for parallax seconds to be useful.
