HD 86264 b is an extrasolar planet which orbits the F-type main sequence star HD 86264, located approximately 237 light years away in the constellation Hydra.[1] The planet is considered to orbit in an eccentric path around the star with a period of about four years. This planet can be as close as 0.86 AU to as far as 4.86 AU. It has minimum mass seven Jupiter masses and orbits at a distance of 2.86 astronomical units. This planet was detected by radial velocity method on August 13, 2009.
An estimate of the planet's inclination and true mass (~9.81 MJ) via astrometry, though with high error, was published in 2022.[2]
