Stephenson 2-18 (Stephenson 2 DFK 1) is currently the largest star known. The red supergiant or hypergiant star has an estimated radius 2,150 times that of the Sun. However, the value is highly uncertain because it is significantly larger than stellar evolution theory predicts. The upper limit on stellar size is around 1,500 solar radii.
