What is Upsilon Grus

Upsilon Gruis is a double in the Crane whose components are separated by more than a degree on the sky —an enormous gap for a stellar pair—, with a marked difference in brightness between the two. The primary is a white main-sequence star, young and hot, set at 285 light-years inside one of the southern constellations charted by Dutch navigators.
