Castor is the alpha star and is made up of two blue-white spectroscopic double-stars and a red dwarf double, so Castor is actually a total of six stars, two of which can be seen by small telescopes.
The beta star of Gemini is Pollux. The two bright stars of Gemini are Castor and Pollux. Although Pollux is the brightest star in Gemini, Castor was named alpha-Gemini (despite being second brightest), therefore, Pollux is beta-Gemini. Pollux is the one more southerly and easterly.
Pollux, the head of the more easterly of the two twins (who is also named Pollux). Interestingly (and somewhat confusingly for people who think the designations run in order of brightness), Pollux is actually Beta Geminorum, not Alpha Geminorum (aka Castor).
Castor is one of the twin sons of Zeus and Leda along with Pollux the twins of the constellation Gemini.

I agree with your correspondent 'Wiki User'', However, from Classical Greece, Pollux was one of a pair of twins. The other twin was 'Castor'. You will find both stars , Castor & Pollux, in the constellation of Gemini, the heavenly twins.
Castor is the second brightest star in the constellation Gemini.
Yes, otherwise it wouldn't be a constellation
