This object is more massive than a planet (55 ± 15 MJ), but less massive than a star (0.052 MSun). The radius of the brown dwarf is about that of Jupiter (or one-tenth that of the Sun). Its surface temperature is 2600 ± 150 K, which is about half that of the Sun. Its luminosity is 0.08–0.05% of that of the Sun. Its age is only 120 million years compared to the Sun's age of 4.6 billion years.
