HIP 113561
Variable starWhat is HIP 113561
Listed as a yellow Sun-like star of Cassiopeia, its distance baffles: 326,200 light-years places it beyond any ordinary Milky Way star —likely a peculiar luminosity or a still ill-measured distant giant. The figure alone humbles the human calendar: when that photon set out, Homo sapiens had not yet walked the Earth.
