Some more wild facts about it:

the star has twice the mass of the sun but is only 32km across

TIL the Roman Emperor was on good terms with Attila the Hun until his sister sent Attila her engagement ring and asked for help to escape betrothal to a senator. Attila took this as a marriage proposal and demanded half the western empire as dowry. When the Emperor refused, Attila invaded.
