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 to 1,549 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.
