'''Zeta Scorpii''' (ζ Sco, ζ Scorpii, HD 152236) is a [[Bayer designation]] shared by two stars in the [[constellation]] of [[Scorpius]].<ref name=constellation-guide/>Zeta-1 Scorpii is a [[hypergiant|hypergiant star]] whereas Zeta-2 Scorpii is a [[giant star]]. Although these stars appear only 7&nbsp;[[arcminute]]s apart in the night sky, they only form a [[binary star|visual binary]], meaning they only appear to be close to one another as they lie along the same line of sight. In fact, Zeta-1 Scorpii is 40 times further away than Zeta-2 Scorpii.<ref name=illinois>{{cite web|url=http://stars.astro.illinois.edu/sow/zeta1sco.html|title=ZETA-1 SCO|accessdate=2019-08-30|author=Jim Kaler|publisher=http://stars.astro.illinois.edu|work=Stars}}</ref> The star Zeta-1 Scorpii is one of the most luminous stars known, thought to be nearly a million times brighter than the [[Sun]]. This article discusses Zeta-1 Scorpii unless explicitly said.
