Its story

43 Ursae Majoris is an orange giant 357 light-years away, an angular neighbour of 42 UMa in the sky of the Great Bear. Though they look almost glued together, their light comes from very different epochs and distances: the physical gap is many light-years. It is a recurring illusion of the night sky, where two points near to our eye may live in separate cosmic rooms. Its light set out in the early seventeenth century, in the thick of the telescopic revolution.
