VFTS 682 is a Wolf-Rayet star in the Large Magellanic Cloud.[1] It located in an active star-forming region, at a projected distance of approximately 30 pc northeast of the massive cluster R136 in the Tarantula Nebula. It is about 150 times the mass of the sun, which makes it one of the most massive stars known. The existence of this evolved star of 150 M implies that it was previously more massive and thus more massive than the expected theoretical limits.[2] VFTS 682 is also very bright, at 3.2 million solar luminosities.
