What is 10 Leporis
10 Leporis is a white A-type star around 272 light-years away, in the Hare forever fleeing Orion across the southern reaches of winter. Its white hue marks a surface hotter than the Sun's, young by stellar standards, with the bright luminous signature characteristic of A-type stars. The light we see tonight broke free as the Treaty of Utrecht was being signed and Europe was redrawing its maps.
