The whole system will end when the primary explodes, sending B out on its own (if it doesn't explode as well). C is the closest to the AB pair, about 3,900 AU away. The visual binary AB has recently been studied by Heintz, and a solution to its orbit and a distance was determined. It has an apparent magnitude of 8.79.

The brightest star in the constellation is normally given the Alpha designation, there are exceptions such as Pollux which is Beta Geminorum. σ Orionis visual magnitude is 3.81. A and B will end their lives as spectacular supernova explosions, while the smaller C, D, and E components will end their lives as white dwarfs after briefly expelling their atmospheres as planetary nebulae. Abstract. Caballero et al.
