VV Cephei is another one of the red super giant stars located in our galaxy. It is also an eclipsing binary star system with a much smaller companion star that is close enough to draw off some of outer layers of the primary star. The orbital period of the pair is around 20 years. The interaction of the secondary star pulling off the outer layers makes for some interesting spectroscopic variations as the stars eclipse one another.
