The last stars in the list are familiar nearby stars put there for comparison, and not among the most luminous known. It may also interest the reader to know that the Sun is more luminous than approximately 95% of all known stars in the local neighbourhood (out to, say, a few hundred light years), due to enormous numbers of somewhat less ...
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
A star is a massive luminous spheroid astronomical object made of plasma that is held together by its own gravity.Stars exhibit great diversity in their properties (such as mass, volume, velocity, stage in stellar evolution, and distance from Earth) and some of the outliers are so disproportionate in comparison with the general population that they are considered extreme.
R136c is a star located in R136, a tight knot of stars at the centre of NGC 2070, an open cluster weighing 450,000 solar masses and containing 10,000 stars. [5] At 142 M ☉ and 3.8 million L ☉, it is the one of the most massive stars known and one of the most luminous, along with being one of the hottest, at over 40,000 K.
R136a1 (short for RMC 136a1) is one of the most massive and luminous stars known, at nearly 200 M ☉ and nearly 4.7 million L ☉, and is also one of the hottest, at around 46,000 K. It is a Wolf–Rayet star at the center of R136 , the central concentration of stars of the large NGC 2070 open cluster in the Tarantula Nebula (30 Doradus ) in ...

On average it has an absolute magnitude of −9.5, making it visually one of the most luminous stars known. Recently imaged and measured by the CHARA array in 2024, its diameter measures between 564 and 700 times that of the Sun, approximately 879,000,000 kilometers (5.88 AU; 546,000,000 mi), or 2.6 to 3.3 times the size of Earth's orbit.
It is a suspected luminous blue variable (LBV), although it has not shown the characteristic spectral variations. A visual band light curve for Wray 17-96, plotted from ASAS-SN data [ 9 ] Wray 17-96 has an absolute bolometric magnitude of −10.9 (1.8 million times the Sun's luminosity ), making it one of the most luminous stars known.
