[...] is best identified by its two brightest stars, Castor and Pollux. These two are noticeable for being bright and close together on the sky’s dome. [...]

Koichi,
There are no known planets in the Castor system. The fact that there appears to be a planet orbitting Pollux says nothing about Castor or any other star. Also, since Castor is actually a complex multiple star system, gravitational instabilities would make planetary orbits problematic and certainly complicated. That is not to say impossible, but by current understanding, it is probably unlikely that planets in orbits of long-time stability would exist. (But, who knows?)

If Pollux has a Jovian planets orbiting around it, so do Castor has any planets orbiting around it? Do anyone think that any planet ever orbits around any star of Castor?

Debbie, look quick. They are almost gone now and will not return until late summer to early fall, and then in the early morning.

I am afraid that I do not know if there is any specific historic evidence that Castor was once the brighter of the two other than the fact that it does carry the alpha designation normally reserved for the brighter star. This designation was given, I believe, about 400 years ago in Johann Bayer’s Uranometria, suggesting that if Castort has faded to a fainter magnitude, it has done so quite recently astronomically speaking.

I’ve read that in classical antiquity Castor was the brighter of the pair. Is that true?

It is believed that Zeus came from a star between Pollux and Castor. Today we believe that star to be a galaxy!
