Which two stars are located in the constellation Gemini?

The two stars that are located in the constellation Gemini are Castor and Pollux. These twin stars are among the most well-known in the night sky and represent the mythological twins in Roman and Greek mythology. Castor is a binary star system, while Pollux is a giant star, both of which can be easily identified from Earth due to their brightness and proximity to each other in the sky.

In contrast, the other pairs of stars listed belong to different constellations. Mizar and Alcor are part of the Big Dipper in Ursa Major. Betelgeuse and Rigel are prominent stars in the constellation Orion, while Aldebaran is located in Taurus and HL Tau is a young star in the same region of the Milky Way. Therefore, the choice of Castor and Pollux as the stars in Gemini is a clear and well-supported answer.
