Winter Hexagon over Manla Reservoir. Car headlights shining along the shores of Manla Reservoir, Tibet, China, with the Winter Hexagon rising in the night sky. The Winter Hexagon is a celestial asterism with vertices at the bright stars Rigel, Aldebaran, Capella, Pollux/Castor, Procyon, and Sirius. Here, the band of our Milky Way Galaxy runs through the centre of the Winter Hexagon, while the Pleiades open star cluster and California Nebula are visible just above.
