Nu-2

Its story

Nu-2 Boötis is a white type A star sitting about 388 light-years away, toward the northern end of the Herdsman, just beneath the Great Bear's tail. Together with its twin Nu-1 it forms an optical pair visible to the naked eye under clean skies: two points of similar brightness that perspective happens to set side by side, with no real gravitational bond. A double of the sky, not of space.
