Castor
Multiple-star system in Gemini, the visual twin of Pollux. What looks like one star is a nest of pairs, including eclipsing variables. Look for it while tracing Gemini on a dark night.
Gaia has no usable parallax for this star (common for bright multiples). Distance uses the Hipparcos parallax instead.
