HIP 29735
Hot blue starWhat is HIP 29735
On the back of the Greater Dog burns a hot B-class star, blue-white, 407 light years away. The light reaching the eye tonight loosed itself around 1618, just as the Thirty Years War was erupting across Europe. Hot-blue by temperature: one of those stellar embers whose surface comfortably exceeds 10,000 degrees, shining with a cutting brilliance even from such depth.
