What is 22 Vulpecula

22 Vulpeculae is an Algol-type eclipsing binary catalogued as variable by Parsons and Abe in 1983, around 1,900 light-years away in the little Fox. The primary is a G-type bright giant, more than four times the Sun's mass and nearly a hundred times its radius; it sweeps a 249-day orbit with a far hotter B-type companion. The light we see tonight began its journey at the close of the Roman Empire.
