Stephenson 2-18 new Largest star [size comparison]

In this simulation video I made Stephenson 2-18 a largest red hypergiant star and Sun 3D model to compare their size and color as you can see the red hypergiant star is 2158 times bigger than the Sun, it means if it replace the sun so it will engulf the orbit of Saturn. The star temperature is 3200 Kelvin which is close to Proxima centauri temperature. Its luminosity is 440,000 times the Sun&Lum. The distance of star is 20,000 light-years away in Stephenson 2 open cluster. #CoolLargeStar
