What is 11 Orionis

11 Orionis is a white A-type star whose brightness drifts in faint oscillations, an almost imperceptible breathing of its surface. It lies around 365 light-years away in the northern reaches of Orion, far from the famous belt yet inside the same mythic rectangle that has guided sailors and shepherds alike. Its light has crossed space during the centuries that separate Spanish Habsburg shipyards from today's digital cameras.
