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]
