Nu-2

Its story

Nu-2 Draconis forms, together with its twin Nu-1, one of the most famous double stars of the northern sky, separable even with decent binoculars within the body of the Dragon. It lies 99 light-years away and is itself a spectroscopic binary on a 38-day orbit, with two chemically peculiar Am stars. Arab astronomers counted it among the Mother Camels. The visual pair is not gravitationally bound: they travel together because they share an origin.
