What is Sualocin

Sualocin is the brightest star of Delphinus and hides one of the few jokes ever inscribed in the sky. In 1814, the Italian astronomer Niccolò Cacciatore Latinised his own name as «Nicolaus Venator» and reversed it letter by letter to christen this star, which has appeared in official catalogues ever since. It is a hot blue-white B-type star 254 light-years away, young and bright, whose humble origin as a signed wink contrasts with the majesty of its light.
