(nearby binary star with red dwarf and brown dwarf)
Scholz's Star (WISE 0720-0845) is a binary system
22 light-years away with a red dwarf
(M-type star) of 86 Jupiter masses
and a brown dwarf of 65 Jupiter masses.
Though nearby, it is much too dim to see without a telescope
and was discovered in 2013.
Given the trajectory of its motion, it passed close to the
solar system 70,000 years ago (52000 AU or 0.25 parsecs
or 0.82 light-years).
At its closest, its apparent magnitude was +11.4.
