    Discovery

    DENIS-P J082303.1-491201 b was discovered by Sahlmann et al. (2013) using the ESO telescopes at the La Silla Paranal Observatory. [1] It is part of an ultracool binary system. [1]

    Properties

    It is located 20.77 parsecs (67.7  ly ) from Earth. At 28.5±1.9  MJ, [2] it is listed as among the most massive planets in the NASA Exoplanet Archive.

    It orbits the nearby L1.5-type brown dwarf DENIS-P J082303.1-491201, which is 7.5±0.7% the mass of the Sun, [1] and has an orbital period of about 246 days. [1] [2]
