A bright asterism of the northern winter sky Winter Triangle  (part of Winter hexagon) . Its corners are the three 1st-magnitude stars Betelgeuse (α Ori), Procyon (α CMi), and Sirius (α CMa).

These three stars are three of the ten brightest objects, as viewed from Earth, outside the Solar System. Betelgeuse is also particularly easy to locate, being a shoulder of Orion, which assists stargazers in finding the triangle. Once the triangle is located, the larger hexagon may then be found.

Several of the stars in the hexagon may also be found independently of one another by following various lines traced through various stars in Orion.

The stars in the hexagon are parts of six constellations. Counter-clockwise around the hexagon, starting with Rigel, these are Orion, Taurus, Auriga,Gemini, Canis Minor, and Canis Major.
