HD 152082 is an A-type shell star[9] in the southern constellation of Ara. It is a giant star[9] that has expanded away from the main sequence and is now 4.5 times larger than the Sun and 112 times as luminous.[6]
HD 152082 has a thirteenth magnitude companion at an angular separation of 6.8″ along a position angle of 329° (as of 2000),[10] but it has a much smaller parallax than the brighter star and is much further away.[11]
