The Winter Hexagon outlined in the night sky. The brightest “star” inside is Mars, just passing through. Orion’s three-star belt is near the hexagon’s lower corner; his foot, Rigel, is the bottommost star. Clockwise from there are Sirius, Procyon, Pollux and Castor, Capella, and Aldebaran. Betelgeuse is inside the hexagon, above Orion’s belt.
