6 Lyn is an orange K-type dwarf (about 1.32 solar masses, 4,941 K, 4.94 solar radii), 54.7 light-years from Earth. 6 Lyn b is a 1.88-Jupiter-mass companion, with an orbital period of 2.52 years, at 2.028 AU from its star, discovered in 2008 via radial velocity. The planet betrayed itself through the star's reflex motion — a technique that first revealed worlds around Sun-like stars in the 1990s and remains a workhorse of exoplanet discovery. 6 Lyn b circles in the outer system, comparable to the Jupiter region.
