"This redshift corresponds to a distance of 120Mpc or 400 million light years (using H₀ = 75km/s/Mpc and q₀ = 0.1). At the distance of the group, this corresponds to a group diameter of 52kpc, i.e., the group is approximately 170,000 light years across". Archived from the original on 19 February 2020.
