Its story

Castor shines in Gemini just 50.9 light-years away, close enough to count as a cosmic neighbour. It is a white class-A star that looks like a single point to the naked eye, though telescopes reveal a tangled stellar family hiding behind it. To the ancient Greeks it stood beside Pollux, the divine twins of Leda, horsemen and patrons of sailors who prayed for clear weather.
