DENIS-P J020529.0−115925 is abrown dwarfsystem in theconstellation ofCetus. It is located 64 light-years (19.8 parsecs) away, based on the system'sparallax.[4] It was first found in theDeep Near Infrared Survey of the Southern Sky.
This is a triplebrown dwarf system: objects that do not have enough mass to fusehydrogen like stars. The two brightest components, designated A and B respectively, are bothL-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 aT-type object.[2] It is separated about 1.9astronomical units (au) from B, and based on a total mass of 0.1 M☉, the two may orbit each other every 8 years.[2]
