RSGC1-F01
RSGC1-F01 is a red supergiant located in the RSGC1 open cluster in the constellation of Scutum. The radius was calculated to be around 1,530[2] times that of the Sun (the radius is calculated by applying the Stefan-Boltzmann law), making it one of the largest stars discovered so far. This corresponds to a volume 3.58 billion times bigger than the Sun. If placed at the center of the Solar System, the photosphere would engulf the orbit of Jupiter.
