HD 131664 is an 8th magnitude G-type main sequence star located approximately 181 light-years away in the constellation of Apus.
On October 26, 2008, a brown dwarf was discovered along with five other planets (BD-17°63 b, HD 145377 b, HD 153950 b, HD 73267 b, and HD 20868 b). This brown dwarf has mass of at least 18.15 times that of Jupiter and orbits in a long-period, eccentric orbit. Follow-up studies with the Hipparcos satellite adjusted the predicted mass of the companion to 23 times that of Jupiter (minimum of 18 and maximum of 49 Jovian masses).
