Orion
Orion (Orionis)
Orion is arguably the most recognizable and spectacular constellation in the entire night sky, visible from both hemispheres between November and February. Named after a giant hunter in Greek mythology, it features the famous 'Orion's Belt' - three bright stars perfectly aligned in a row. The constellation contains two first-magnitude stars (Rigel and Betelgeuse) and the magnificent Orion Nebula (M42), one of the brightest nebulae visible to the naked eye.
📜 Mythology
Orion was a giant huntsman born to the sea god Poseidon, who granted him the ability to walk on water. He was renowned as the greatest hunter in the world and boasted that he could kill any animal on Earth. According to one myth, the goddess Artemis fell in love with him, but her twin brother Apollo, disapproving of the relationship, tricked her into killing Orion with an arrow. Another version tells that Gaia sent a giant scorpion to kill him after his boast, which is why Orion and Scorpius are placed on opposite sides of the sky.
