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 ...
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
Nevertheless, Clowes et al. found independent support for the reality of the structure from its coincidence with Mg II absorbers (once-ionised magnesium gas, commonly used to probe distant galaxies). The Mg II gas suggests that the Huge-LQG is associated with an enhancement of the mass, rather than being a false positive identification.
This is a list of the largest cosmic structures so far discovered. The unit of measurement used is the light-year (distance traveled by light in one Julian year; approximately 9.46 trillion kilometres).

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 ...
Earlier observations found that, if placed at the center of our solar system, the massive star Betelgeuse would stretch out beyond the orbit of Jupiter. This new study finds its body would only ...
The chemical composition of this heavenly body, unlike the sun and most of the Milky Way, are similar, if not the same, to stars discovered billions of years ago in a "much younger" universe, the ...
