RSGC1-F02 is a red supergiant star. It belongs to the open cluster RSGC1. It is located in the constellation of Scutum. Its radius was calculated to be between 1,499[5] to 1,549[6] times that of the Sun. The radius is calculated using the Stefan-Boltzmann law. It is one of the largest stars ever discovered. The star has a volume of 3.37 or 3.72 billion times bigger than the Sun.

If RSGC1-F02 was placed at the center of the Solar System, its photosphere would reach the orbit of Jupiter.
