IRAS 05280-6910
IRAS 05280–6910 (also known as LMC 582) is a red supergiant star or OH/IR supergiant star.[1] It is located in the Large Magellanic Cloud and it is also the most reddened object in the Large Magellanic Cloud, far more than the redness that the famous red supergiant WOH G64 emits. Its radius is 1,367 to 1,736 times that of the Sun, making it one of the largest stars found so far. If it was placed at the center of the Solar System, its photosphere would reach and eat the orbit of Jupiter. It is estimated that the star loses 5.4×10−4 M☉ (Solar mass) per year, this mass loss rate is the highest known for any red supergiant star.
