RSGC1-F01
RSGC1-F01 is a red supergiant located in the RSGC1 open cluster in the constellation of Scutum. Its radius was calculated to be between 1,435[1] and 1,551[4] times that of the Sun (the radius is calculated by applying the Stefan-Bolzmann law), making it one of the largest stars discovered so far. This corresponds to a volume 2.95 and 3.73 billion times bigger than the Sun. If placed at the center of the Solar System, its photosphere would engulf the orbit of Jupiter.
