minus-square Allero ( @Allero@lemmy.today ) linkfedilinkEnglish2•16 days agoThey normally use parallax-seconds, i.e. parsecs, for long distance objects.
minus-square m0darn ( @m0darn@lemmy.ca ) linkfedilinkEnglish2•16 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.
