Stephenson 2-18 is now considered to be among the largest known stars, if not the largest, with a radius of 2,158 solar radii. UY Scuti on the other hand is about 1,700 times greater than the radius of the sun. It is also among the most luminous cool supergiant stars, with a luminosity of 440,000 solar luminosity.
The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun. And it's not alone in dwarfing Earth's dominant star.
