What is 64 Geminorum

64 Geminorum is a white A-type star 176 light-years away, lit within the body of the celestial Twins. Outshone by the fame of Castor and Pollux, it shares the same winter sky territory, that stretch where the Milky Way crosses the brothers' interlocked silhouette. Its light has been travelling since the late nineteenth century.
