オリオン座 猎户座 獵戶座 오리온자리
Orion is an equatorial [[constellation]], named after the mythological hunter Orion in Greek mythology. Its brightest stars are [[Betelgeuse (star)|]], part of the "Winter triangle":https://en.wikipedia.org/wiki/Winter_Triangle, and Rigel, part of the "Winter Hexagon":https://en.wikipedia.org/wiki/Winter_Hexagon.

Orion is one of the brightest and most easily recognizable constellations. Its 7 brightest stars form an hourglass "[b]⟩⟨[/b]" shape with red Betelgeuse at the top left and blue Rigel at the bottom right. At the center of the shape lies a 3-star asterism known as the "[i]Belt of Orion[/i]":https://www.glyphweb.com/esky/constellations/orionsbelt.html, beneath which lies another asterism called the "[i]Sword of Orion[/i]":https://www.glyphweb.com/esky/constellations/swordoforion.html (see post #8405 for reference). In addition to the hourglass shape, other stars in the constellation form patterns that depict a stick figure of Orion with one arm holding a bow (in other interpretations, a shield or hide) and the other arm raised (in other interpretations, holding a club or sword).
