There are two major asterisms that dominate the winter night sky: the Winter Triangle and the Winter Hexagon. The bright stars Sirius in Canis Major and Procyon in Canis Minor are part of both. The Winter Triangle is formed by these two stars with Betelgeuse in Orion, and the Winter Hexagon is formed by a total of seven stars: Sirius, Procyon, Castor and Pollux in Gemini, Capella in Auriga, Aldebaran in Taurus and Rigel in Orion.
