HIP 75257
Highly luminous starWhat is HIP 75257
Orange, luminous, profoundly distant —1942 light-years away— in Boötes, the celestial herdsman. Its light departed around 84 AD, when emperor Domitian ruled Rome and gladiators were inaugurating the newly finished Colosseum. This K giant, far brighter than our Sun, released back then the photon that any human catches tonight.
