UX Antliae is a post-AGB and R Coronae Borealis variable star that has a base apparent magnitude of around 11.85, with irregular dimmings down to below magnitude 18.0.^[8]

Researchers David Kilkenny and J.E. Westerhuys of the South African Astronomical Observatory confirmed that UX Antliae was an R Coronae Borealis variable in 1990 after noting the similarity of its spectrum to the RCB star W Mensae.^[9] It had been suspected of being one since 1940, but had been little-studied and exhibited no characteristic declines between 1975 and 1990.^[4]

Assuming that its absolute magnitude is around -5, it has been estimated as lying 25000 parsecs distant from Earth.^[4] Kilkenny and Westerhuys noted that its spectrum fit with that of a star of spectral class F, although was deficient in hydrogen.^[9] It has around 70% the mass of the Sun and an effective (surface) temperature of around 7000 K.^[7]
