Where the name comes from

Castor, a name of Greek origin, belongs to the constellation Gemini, forever linked to the myth of the twin brothers Castor and Pollux. Castor was mortal, while Pollux was immortal, a son of Zeus. Their bond was so profound that when Castor died, Pollux chose to share his immortality, spending half his time in the Underworld with his brother. Ancient observers saw Castor as a symbol of cleverness and skill, particularly in horsemanship. This star, one of the brightest in Gemini, was noted for its association with intellectual pursuits and artistry, reflecting the duality and depth of the twins' mythological legacy.
