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 M J ,[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]
