WOH G64
WOH G64 is a symbiotic binary with a yellow hypergiant star in the constellation of Dorado. It was the first star outside of the Milky Way to have a direct image taken of it.
It was formerly thought to be one of the largest known stars in the known universe with a radius of about 1,540 times that of the Sun,[1] however, in 2014 it rapidly transitioned into a yellow hypergiant, shrinking to a smaller radius 800 times that of the Sun, with a temperature of 4,700 kelvin.[2]
WOH G64 is surrounded by a thick dust envelope of about a light year in diameter. This envelope is made of expelled material and is three to nine times the Sun's mass. It was created by the strong stellar wind.[3] If placed at the center of the Solar System, the star's photosphere would engulf the orbit of Mars.
