The constellation represented by the stars Castor and Pollux is Gemini. This constellation is often associated with the mythological twin brothers in Greek mythology, who are known for their close bond and shared adventures. Castor and Pollux are the two brightest stars in Gemini, with Pollux being the more luminous of the two.

The name Gemini itself means "twins" in Latin, directly reflecting the relationship between these two stars. This constellation is easily recognizable in the night sky and is located on the ecliptic, the path that the Sun and planets follow across the sky. The presence of these prominent stars further contributes to Gemini's identification as one of the zodiac constellations.
