}}{{Starbox end}}Iota Antliae (ι Ant, ι Antliae) is the Bayer designation for a star in the southern constellation of Antlia. It has an apparent visual magnitude of +4.60,[3] making it a faint naked eye star. From parallax measurements, the distance to this star can be estimated as {{Convert|202 ± 2|ly|pc|abbr=off|lk=on}}.[1] The spectrum of Iota Antliae matches a stellar classification of K1 III,[4] indicating that this is an evolved star that is now in its giant phase. It is a core helium fusing star that is classified as a member of the red clump evolutionary branch.[19]References1. ^1 2 3 {{cite DR2|5394951821153092864}}
