Distances

Astrophysical objects, surveys, and concepts listed by distance, etc.
(See More Detailed List of Distances below)
(The longest distances and earliest times below are somewhat off: they are calculated from cosmological redshift using Hubble's Law with a Lorentz-factor correction and estimated Hubble Constant 70 km/Mpc, but with no accommodation for Λ or the universe's density. Recent actual age determinations are in the vicinity of 13.8 billion years. The shortest redshifts below are calculated from distance using Hubble's Law; they are not the object's actual redshift. )
