The most massive star discovered to date is R136a1. This is a star that is over 300 times more massive than the sun. It is located 165,000 light years away in the Large Magellanic Cloud. The image shows the relative sizes of young stars, from the smallest “red dwarfs”, weighing in at about 0.1 solar masses, through low mass “yellow dwarfs” such as the Sun, to massive “blue dwarf” stars weighing eight times more than the Sun, as well as the 300 solar mass star named R136a1
