DENIS J081730.0−615520 (also known as 2MASS 08173001−6155158) is a T-type brown dwarf 17 light-years (5.2 parsecs) away in the constellation Carina. It was discovered by Etienne Artigau and his colleagues in April 2010.[2] The brown dwarf belongs to the T6 spectral class, with a photosphere temperature of about 1000 K.[4] It has a mass of about 15 MJ (Jupiter masses) or about 1.5% the mass of the Sun.[failed verification]
DENIS J081730.0-615520 is the fourth-nearest isolated T dwarf to the Sun (after
multiple star systems.[7] It is also the brightest T dwarf in the sky (in the J-band); it had been missed before due to its proximity to the galactic plane.[2]
