DENIS-P J082303.1−491201 b
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,[4] an L1.5-type brown dwarf in the constellation Vela.[2]
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]
