Claim: Zeta Antliae is in the Antlia Constellation (originally Antlia Pneumatica, established by Nicolas-Louis de Lacaille in the 18th century) with an apparent magnitude of 5.91 and a spectral type of A9 IV.
Evidence: Zeta Antliae is the Bayer designation for a star in the southern constellation of Antlia, the air pump. Originally Antlia Pneumatica, the constellation was established by Nicolas-Louis de Lacaille in the 18th century. With an apparent visual magnitude of 5.91, it is a relatively faint star that requires dark suburban skies for viewing with the naked eye. The spectrum of this star matches a stellar classification of A9 IV, where the luminosity class of IV indicate that this is a subgiant star that is evolving away from the main sequence as the supply of hydrogen at its core is becoming exhausted.
