It is the most massive star that has a Bayer designation. It was only discovered to be (at least) two stars in the past few decades. Both the obscuring clouds and the great distances also make it difficult to judge whether the star is just a single supermassive object or, instead, a multiple star system. A number of the "stars" listed below may ...
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 ...
A yellow hypergiant, one of the rarest types of stars. V838 Monocerotis: 464 [81] L/T eff: During the 2002 Red Nova, the star's radius may have increased up to 3,190 R ☉. [82] Pistol Star (V4647 Sagittarii) 420 [83] L/T eff: One of the most luminous stars known. La Superba (Y Canum Venaticorum) 344 [84] L/T eff: Mira (ο Ceti A) 332–402 [85] AD
UY Scuti was analyzed to be the largest and the most luminous of the three stars measured, at 1,708 ± 192 R ☉ (1.188 × 10 9 ± 134,000,000 km; 7.94 ± 0.89 AU) based on an angular diameter of 5.48 ± 0.10 mas and an assumed distance of 2.9 ± 0.317 kiloparsecs (kpc) (about 9,500 ± 1,030 light-years) which was originally derived in 1970 ...
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 ...
But unlike the jet formed by J1601+3102, Porphyrion was found 7.5 billion light-years away from Earth in what’s called the “nearby” universe, rather than the early universe, according to the ...

A massive galaxy filament, called the Norma Wall (also called Great Attractor Wall [11]) is located at the center of the supposed position of the Great Attractor. The Norma Wall contains the clusters Pavo II, Norma, Centaurus-Crux and CIZA J1324.7−5736. The most massive cluster in this region is the Norma supercluster. [12]
