UY Scuti (BD-12°5055) is a red supergiant star, located 5,900 light-years away in the constellation Scutum. It is also a pulsating variable star , with a maximum brightness of magnitude 8.29 and a minimum of magnitude 10.56, which is too dim for naked-eye visibility.
In the latest stages of mass loss, before a star explodes, surface helium may become enriched to levels comparable with hydrogen. ... UY Scuti; VY Canis Majoris ...
UY Scuti: 909 [23] L/T eff: Initially reported 1,708 R ☉, making it the largest star, a 2023 measurement put the radius at a smaller value of 909 R ☉ based on the multimessenger monitoring of supernovae. [23] NR Vulpeculae: 908 [23] – 923 +62 −50 [25] L/T eff: KU Andromedae (IRC +40004) 900 [56] – 1,044 [55] L/T eff: V774 Sagittarii ...
Stephenson 2 DFK 1, also known as RSGC2-01 [a] or St2-18, is a red supergiant (RSG) or possible extreme red hypergiant [2] (RHG) star in the constellation of Scutum.It lies near the open cluster Stephenson 2, which is located about 5.8 kiloparsecs (19,000 light-years) away from Earth in the Scutum–Centaurus Arm of the Milky Way galaxy, and is assumed to be one of a group of stars at a ...
A hypergiant (luminosity class 0 or Ia +) is a very rare type of star that has an extremely high luminosity, mass, size and mass loss because of its extreme stellar winds.The term hypergiant is defined as luminosity class 0 (zero) in the MKK system.
Roblox occasionally hosts real-life and virtual events. They have in the past hosted events such as BloxCon, which was a convention for ordinary players on the platform. [46] Roblox operates annual Easter egg hunts [52] and also hosts an annual event called the "Bloxy Awards", an awards ceremony that also functions as a fundraiser. The 2020 ...
Then that would be better suited to be the lower range of the estimate, which works as well as what is done in UY Scuti, which retains the 1,708 R ☉ value while the list considers the smaller, 825 R ☉. We can do the same in order to lessen the push for DFK 1 on the radius of 2,150 R ☉. SkyFlubbler 23:05, 20 August 2023 (UTC)
NML Cygni or V1489 Cygni (abbreviated to NML Cyg or V1489 Cyg) is a red hypergiant [4] or red supergiant (RSG) in the constellation Cygnus.It is a likely candidate for the largest star currently known, although its radius is not very certain, and is also possibly one of the most luminous and massive cool hypergiants, as well as one of the most luminous stars in the Milky Way.
