Luhman 16

Binary brown dwarf, third closest star system.
(Redirected from WISE 1049-5319)

Luhman 16 is a binary brown dwarf in the southern constellation Vela at 6.6 light-years from the Sun. It is also known as WISE 1049-5319.

The Luhman 16 binary brown dwarf is the yellow disc at the center of this WISE image. The two individual stars are seen as one here.

These are the nearest known brown dwarfs to the Solar System, and the closest system discovered since Barnard's Star in 1916.[1][2]

The primary has a stellar classification of L8 ± 1, and the secondary is probably near the L/T transition. The pair orbit each other at a distance of about 3 AU with an orbital period of about 25 years.[1]
