What class is Spica in?
class B1 III-IV
It belongs to the spectral class B1 III-IV. With a mass more than 10 times that of the Sun, Spica A is one of the nearest stars to Earth that are massive enough to end their life in a Type II supernova event. The primary component is responsible for about 80 percent of the light that comes from the star system.
