Binary systemWhat is Guniibuu B
Guniibuu B is a very close neighbour, just 19 light-years away, a member of the binary system the Kamilaroi people of Australia named after a small reddish bird. It is an orange K-type star, cooler and smaller than the Sun, gravitationally bound to a companion with whom it shares a long orbital dance. The light perceived tonight left its surface in a recent era, roughly the span between two human generations.
