RSGC1-F02 is a red supergiant located in the RSGC1 open cluster in the constellation of Scutum. Its radius was calculated to be between 1,499[1] and 1,549[3] or 1,128[2] times that of the Sun (the radius is calculated applying the Stefan-Boltzmann law), making it one of the largest stars discovered so far. This corresponds to a volume 3.37 and 3.72 billion times bigger than the Sun. If placed at the center of the Solar System, its photosphere would engulf the orbit of Jupiter.
