MOA-2007-BLG-197Lb is a brown dwarf discovered in August 2015 by the MOA collaboration.[1] It is the first brown dwarf found by the microlensing method to orbit a solar-type star. However, Ranc et al.'s 2015 discovery paper doesn't include the system's constellation or coordinates.
Its host star, MOA-2007-BLG-197L, is a G-K dwarf with 0.82 ± 0.04 solar masses.
