That list is available at list of quasars. 8C 1435+63: 1994–1997: z=4.25 This is a radio galaxy. At the time of its discovery, quasar PC 1247-3406 at z=4.73, discovered in 1991 was the most remote object known. This was the last radio galaxy to hold the title of most distant galaxy.
These names of stars that have either been approved by the International Astronomical Union or which have been in somewhat recent use. IAU approval comes mostly from its Working Group on Star Names, which has been publishing a "List of IAU-approved Star Names" since 2016. As of February 2025, the list included a total of 492 proper names of stars.
The following is a list of particularly notable actual or hypothetical stars that have their own articles in Wikipedia, but are not included in the lists above. BPM 37093 — a diamond star Cygnus X-1 — X-ray source

A galaxy is a system of stars, stellar remnants, interstellar gas, dust, dark matter, bound together by gravity. The word is derived from the Greek galaxias, literally 'milky', a reference to the Milky Way galaxy that contains the Solar System.

Named for its size, El Gordo ("the fat one") is the biggest cluster found in the distant universe (at its distance and beyond), at the time of discovery in 2011, with a mass of 3 quadrillion suns. The second most massive galaxy cluster next to El Gordo is RCS2 J2327, a galaxy cluster with the mass of 2 quadrillion suns.
Quasars would remain the most distant objects in the universe until 1997, when a pair of non-quasar galaxies would take the title (galaxies CL 1358+62 G1 & CL 1358+62 G2 lensed by galaxy cluster CL 1358+62).
