Scholz's Star

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. Characteristics:

• Monoceros - constellation.
• 07h20m03.254s - right ascension.
• -08deg46m49.90s - declination.
• +18.3 - apparent magnitude.
• 22.2 ly - distance.
• M9.5 and T5.5 - spectral types.
• 0.095 and 0.063 - masses(solar).
• +19.4 - absolute magnitude.
• 82.4 km/s - radial velocity.
• 0.12 arcseconds/year - proper motion.
