Ross 986 is also known as Gl 268. Nearby binary red dwarf star in Auriga. Star A is a flare star known as QY Aurigae. Star B is A's spectroscopic binary pair and they orbit each other in 10.4 days. The pair form a RS Canum Venaticorum variable star, which are two stars whose brightness varies due to their strong magnetic fields due to their rapid rotation, which is accelerated due to tidal effects caused by their proximity. Ultra-precise mass measurements were obtained in 2008. Precise orbital measurements taken in 2012 are the best for any visual binary and compete with the best measurements taken for eclipsing binaries.
