Beta Monocerotis C (Beta Mon C / β Monocerotis C / β Mon C) is a Be star with a mass of approximately 6 solar masses and a luminosity of 1,300 times the Sun's. This star was observed to be double in speckle interferometric observations in 1988, but this has not been confirmed by later infrared observations.
