Magellanic Cloud

WOH G64 is a red supergiant star. It is the largest star in the Large Magellanic Cloud (LMC). It has a radius of 1,800 to over 2,400 times that of the Sun. It is one of the largest known stars.[1]

It is also one of the coolest stars in the LMC, with an effective temperature of 3,400 Kelvin. It is a possible Mira variable.

WOH G64 is surrounded by a thick dust envelope of about a light year in diameter. This has three to nine times the Sun's mass of expelled material. It was created by the strong stellar wind.[2] If placed at the center of the Solar System, the star's photosphere would engulf the orbit of Jupiter.
