This is a list of quasars.
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.
List of quasars
| Quasar | Notes |
|---|---|
| Twin Quasar | Associated with a possible planet microlensing event in the gravitational lens galaxy that is doubling the Twin Quasar's image |
| QSR J1819+3845 | Proved interstellar scintillation due to the interstellar medium |
List of named quasars
This is a list of quasars, with a common name, instead of a designation from a survey, catalogue or list.
| Quasar | Origin of name | Notes |
|---|---|---|
| Twin Quasar | ||
| Einstein Cross |
 | This list is incomplete; you can help by adding missing items. |
List of naked-eye quasars
There are currently no quasars that are visible to the naked eye.
List of multiply-imaged quasars
This is a list of quasars, that as a result of gravitational lensing, appears as multiple images on Earth.
| Quasar | Images | Lens | Notes |
|---|---|---|---|
| Twin Quasar | 2 | YGKOW G1 | First gravitationally lensed object discovered ; Second largest separation between images (6 ″) ; |
| Einstein Cross | 4 | Huchra's Lens | First Einstein Cross discovered |
| RXS J1131-1231 's quasar | 4 | RXS J1131-1231 's elliptical galaxy | RXS J1131-1231 is the name of the complex, quasar, host galaxy and lensing galaxy, together. The quasar's host galaxy is also lensed into a Chwolson ring about the lensing galaxy. The four images of the quasar are embedded in the ring image. |
| SDSS J1004+411 | 5 | SDSS J1004+4112 | First quasar discovered to be multiply-image lensed by a galaxy cluster ; Largest separation between images (15 ″) ; |
| QSO B1359+154 | 6 | CLASS B1359+154 and three more galaxies | First sextuply-imaged galaxy |
| This list is incomplete; you can help by adding missing items. |
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.
| Quasar | Superluminality | Notes |
|---|---|---|
| 3C 179 | 7.6c | Fifth discovered, first with double lobes |
| 3C 216 | ||
| 3C 273 | ||
| 3C 345 | ||
| 3C 380 | ||
| 4C 69.21 (Q1642+690, QSO B1642+690) |
||
| 8C 1928+738 (Q1928+738, QSO J1927+73, Quasar J192748.6+735802) |
||
| PKS 0637-752 | ||
| QSO B1642+690 |
| This list is incomplete; you can help by adding missing items. |
Firsts
| Title | Quasar | Year | Data | Notes |
|---|---|---|---|---|
| First "star" discovered later found to be a quasar | ||||
| First radio source discovered later found to be a quasar | ||||
| First quasar discovered | 3C 48 | 1960 | first radio source for which optical identification was found, that was a star-like looking object | |
| First quasar identified | 3C 273 | 1962 | first radio-"star" found to be at a high redshift with a non-stellar spectrum. | |
| First radio-quiet quasar | ||||
| First host galaxy of a quasar discovered | 3C 48 | 1982 | ||
| First quasar found to seemingly not have a host galaxy | HE0450-2958 | 2005 | If there is a host galaxy, it must be less than 300 ly across or be a dark galaxy | |
| First gravitationally lensed quasar identified | Twin Quasar | The lens is a galaxy known as YGKOW G1 | ||
| First quasar found with a jet with apparent superluminal motion | ||||
