HD 160342 is a star in the southern constellation of Ara. HD 160342 is its Henry Draper Catalogue designation. It has an apparent visual magnitude of 6.35,[10] making it very faintly visible to the naked eye under ideal observing conditions. Based upon parallax measurements, is approximately Script error: No such module "convert". distant from Earth.

In 1971, P. M. Corben announced that HD 160342 is a variable star, a discovery made using a telescope equipped with a photoelectric photometer at the Royal Observatory in South Africa.[11] It was given its variable star designation, V626 Arae, in 1973.[12]

With a stellar classification of M3 III,[4] this is an evolved red giant that is on the asymptotic giant branch.[10] It is a variable star that is classified as irregular,[3] although changes in brightness of 0.1127 magnitudes at the rate of 0.37943 cycles per day (once every 2.6 days) have been detected in Hipparcos photometry.[13]
