Variable starIts story
In the long, winding Eridanus burns a blue star at 790 light-years. Its light departed around the year 1236, when Ferdinand III was conquering Córdoba and medieval Christendom was reorganizing its southern frontier. It is a class B variable, hot and powerful, whose brightness shifts subtly due to atmospheric processes not yet fully understood. Its blue-white hue betrays a surface well above 10,000 K.
