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 [55] – 1,044 [54] 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 ...
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.

Within 1.3 million years it will come as close to 10 light years from Earth, [10] and will be much brighter than Sirius by that time. UY Scuti is a red supergiant and is also one of the largest stars currently known with a radius over 900 times that of the Sun. [11] RSGC1-F01 is another red supergiant whose radius is over 1,450 times that of ...
The actual limit-point mass depends on how opaque the gas in the star is, and metal-rich Population I stars have lower mass limits than metal-poor Population II stars. Before their demise, the hypothetical metal-free Population III stars would have had the highest allowed mass, somewhere around 300 M ☉ .
Our Milky Way galaxy's most common type of star is called a red dwarf - much smaller and less luminous than our sun. But the discovery of a planet at least 13 times Earth's mass orbiting very ...
Westerlund 1 W26 (commonly abbreviated to W26) or Westerlund 1 BKS AS is a red supergiant located at the outskirts of the Westerlund 1 super star cluster.It is one of the largest known stars and the most luminous supergiant stars discovered so far with radius calculated to be in excess of a thousand times the solar radius, and a luminosity of over 200,000 times the solar luminosity.
