HIP 5158 c is an extrasolar planet, orbiting the 10th magnitude K-type main sequence star HIP 5158 about 135 lightyears away from Earth, in the constellation Cetus.^[1]

It orbits its primary star at an average distance (semi-major axis) of 7.7 AU. The actual orbital period is unknown, but is estimated to be somewhere in between 9,018 to 12,200 days. It travels with an eccentricity of 0.14. It also has an estimated mass 15.04 Mj. It was most likely discovered by HARPS on October 19, 2009, together with 29 other planets.
