HD 153053 is double star in the southern constellation of Ara. The brighter component is an A-type main sequence star that may be evolving into a subgiant.[5] It has a twelfth magnitude visual companion at an angular separation of 24.7″ along a position angle of 52°.[9] Mostly likely the two are isolated stars that happen to lie near the same line of sight.[10]
This star displays an excess emission of infrared radiation, suggesting the presence of a disk of dusty debris. This disk is orbiting at a radius of 49 AU from the host star.[7]
