It is located 64 light-years (19.8 parsecs) away, based on the system's parallax.[1] It was first found in the Deep Near Infrared Survey of the Southern Sky.

This is a triple brown dwarf system: objects that do not have enough mass to fuse hydrogen like stars. The two brightest components, designated A and B respectively, are both L-type objects. As of 2003, the two were separated 0.287° along a position angle of 246°.[2]

Component B was observed as elongated, suggesting a third component. This third component, named C, is a T-type object.[2] It is separated about 1.9 astronomical units (au) from B, and based on a total mass of Шаблон:Solar mass, the two may orbit each other every 8 years.[2]
