17.88. 13,500-26,000. SIMBAD. [165] Note that even the most luminous stars are much less luminous than the more luminous persistent extragalactic objects, such as quasars. For example, 3C 273 has an average apparent magnitude of 12.8 (when observing with a telescope ), but an absolute magnitude of −26.7.
Most stars on this list appear bright from Earth because they are nearby, not because they are intrinsically luminous. For a list which compensates for the distances, converting the apparent magnitude to the absolute magnitude, see the list of most luminous stars. Some major asterisms, which feature many of the brightest stars in the night sky
List of most luminous stars: Most luminous star in a transient event Progenitor of GRB 080916C: 2008 V=−40: The star exploded in a gamma-ray burst with the total energy equal to 9,000 supernovae List of gamma-ray bursts: Least luminous normal star 2MASS J0523−1403: 2013 V=20.6: Most energetic star R136a1: 2010 B=-12.5: List of most luminous ...
The brightest stars are completely listed until apparent magnitude of 2 including Polaris. Some of the record holders, like the nearest star, the largest star, the most luminous star in the Milky Way etc. are added to the list. The main purpose for this list is the possibility to compare stars of different categories, like to compare the most ...

List of quasars. This is a list of exceptional quasars for characteristics otherwise not separately listed. 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.
This is a list of hottest stars so far discovered (excluding degenerate stars), arranged by decreasing temperature. The stars with temperatures higher than 60,000 K are included. List [ edit ]
An O-type star is a hot, blue-white star of spectral type O in the Yerkes classification system employed by astronomers. They have temperatures in excess of 30,000 kelvins (K). Stars of this type have strong absorption lines of ionised helium, strong lines of other ionised elements, and hydrogen and neutral helium lines weaker than spectral ...
