IRAS 05280-6910

IRAS 05280-6910 is a red supergiant star or OH/IR supergiant star[5] located in the Large Magellanic Cloud. Its radius is calculated to be more than a thousand times that of the Sun, making it one of the largest stars discovered so far. If placed at the center of the Solar System, its photosphere would engulf the orbit of Jupiter. It has an estimated mass loss rate of 5.4×10−4 M☉ per year, one of the highest known for any red supergiant star.[3]
