Pollux
Gemini originates from the Latin word which means 'twins'. The constellation is related to the mythical Greek twin gods Castor and Pollux.
Pollux is significantly more massive than the Sun and is therefore fairly young (massive stars don't live to be old). It's probably somewhere in the vicinity of three-quarters of a billion years old.
No, Aldebaran and Pollux are different stars. Aldebaran is a red giant star located in the Taurus constellation, while Pollux is a giant star in the Gemini constellation. They can be seen in the night sky as bright objects, but they are distinct celestial bodies with different characteristics.
