• Source: List of quasars

This article contains lists of quasars. More than a million quasars have been observed, so any list on Wikipedia is necessarily a selection of them.
Proper naming of quasars are by Catalogue Entry, Qxxxx±yy using B1950 coordinates, or QSO Jxxxx±yyyy using J2000 coordinates. They may also use the prefix QSR. There are currently no quasars that are visible to the naked eye.




List of quasars


This is a list of exceptional quasars for characteristics otherwise not separately listed




List of named quasars


This is a list of quasars, with a common name, instead of a designation from a survey, catalogue or list.




List of multiply imaged quasars


This is a list of quasars that as a result of gravitational lensing appear as multiple images on Earth.




List of visual quasar associations


This is a list of double quasars, triple quasars, and the like, where quasars are close together in line-of-sight, but not physically related.




List of physical quasar groups


This is a list of binary quasars, trinary quasars, and the like, where quasars are physically close to each other.




= Large Quasar Groups

=

Large quasar groups (LQGs) are bound to a filament of mass, and not directly bound to each other.




List of quasars with apparent superluminal jet motion


This is a list of quasars with jets that appear to be superluminal due to relativistic effects and line-of-sight orientation. Such quasars are sometimes referred to as superluminal quasars.

Quasars that have a recessional velocity greater than the speed of light (c) are very common. Any quasar with z > 1 is receding faster than c, while z exactly equal to 1 indicates recession at the speed of light. Early attempts to explain superluminal quasars resulted in convoluted explanations with a limit of z = 2.326, or in the extreme z < 2.4. The majority of quasars lie between z = 2 and z = 5.

Most distant quasars



In 1964 a quasar became the most distant object in the universe for the first time. 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).
In cosmic scales distance is usually indicated by redshift (denoted by z) which is a measure of recessional velocity and inferred distance due to cosmological expansion.
