Its story

Boötes is a constellation of the northern spring, drawn as a herdsman driving the bears around the pole. Among its lesser stars glows this yellow sun, a sibling in tone and temperature to our own, whose light took about 258 years to arrive. When it set out, Enlightenment astronomers were launching expeditions across the globe to time the transit of Venus and, for the first time, calculate the real size of the Solar System. Today that yellow glow reaches us as a silent echo of those voyages.
