Its story

Epsilon Normae is a blue-white triple some 530 light-years away: the inner pair is a double-lined spectroscopic binary, two nearly identical B4 V twins circling each other every 3.26 days on a slightly eccentric orbit. Far beyond, a third B9 star joins them, separated by 22.8 arcseconds and reachable with steady binoculars in the small southern constellation of the Set Square.
