DENIS-P J082303.1-491201 b (alias 2MASS J08230313-4912012 b) is a substellar object, classified as either an exoplanet or a brown dwarf, orbiting DENIS-P J082303.1-491201, an L1.5-type brown dwarf in the constellation Vela.

Discovery

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

Properties

It is located 20.77 parsecs (67.7 ly) from Earth. At 28.5±1.9 M_J, 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, and has an orbital period of about 246 days.
