Zeta1 Antliae is the Bayer designation for a binary star[3] system in the southern constellation of Antlia. Based upon parallax measurements, the pair are located at a distance of roughly 410 light-years (130 parsecs) from Earth.[1] Both components are rapidly rotating[4] A-type main sequence stars.[3] They have apparent magnitudes of +6.20 and 7.01 and are separated by 8.042 arcseconds.[3] The apparent magnitude of the combined system is +5.76,[2] which is bright enough to be seen with the naked eye in suitably dark skies.
