The Sun's radius is 695,800km, therefore, the star's radius is an estimated 111,328.km. A number represents a stars magnitude, whether apparent/visual or absolute. This prevents the buildup of helium in the stellar cores and prolongs the period of fusion, allowing low-mass red dwarfs to maintain the same spectral type and luminosity for trillions of years before they run out of fuel. Due to its small size, Wolf 359 is fully convective, which means that the helium generated in the stars core is transported to the surface by mass movement of plasma.
