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 ...
Stephenson 2 DFK 2 1,300 ± 300 [12] L/T eff: Another red supergiant, Stephenson 2 DFK 1 has an estimated radius of 2,150 R ☉. However, it is potentially not a member of the Stephenson 2 cluster and also has a distance with an uncertainty of ≳50% due to it only being measured with radial velocities. [12] [24] Stephenson 2 DFK 49: 1,300 ± ...
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.
English: Size comparison of evolved red supergiant star Stephenson 2-18, extreme red hypergiant star VY Canis Majoris and luminous red supergiant star UY Scuti. Bahasa Indonesia: Perbandingan ukuran bintang super raksasa merah berevolusi Stephenson 2-18, bintang hypergiant merah ekstrim VY Canis Majoris dan bintang super raksasa merah bercahaya ...
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 Sun. [12] Scutum contains several clusters of supergiant stars, including RSGC1, [13] Stephenson 2 [14] [15] and RSGC3. [16]

WOH G64 (IRAS 04553-6825) is a symbiotic binary in the Large Magellanic Cloud (LMC), roughly 160,000 light-years from Earth. The main component of this system was once recognized as the best candidate for the largest known star when it was a red supergiant, [7] until it gradually became a yellow hypergiant with half of its original size.
UY Scuti was the largest since Westerlund 1-26, but since UY Scuti has a smaller size estimate than Stephenson 2-18 It should be that Stephenson 2-18 is the largest. It might have been that it was the largest for 6 or 8 years.--THE COLOSSAL GALAXY NAMED IC1101 07:46, 23 July 2020 (UTC) What's past is passed.
