Gliese 15 Ac (also known as Groombridge 34 Ac, GX Andromedae c) is an exoplanet orbiting the nearby red dwarf star Gliese 15 A (Groombridge 34 A, GX Andromedae), which is part of a binary star system located about 11.6 light-years[1] from the Sun. The planet was first proposed in October 2017 using radial velocity data from the CARMENES spectrograph, combined with measurements from the HARPS and HIRES spectrographs,[2] and its existence was confirmed in April 2018 using HARPS-N data.[3] It has a minimum mass 36 times that of Earth and orbits at around 5.4 astronomical units with a period of Шаблон:Convert, an orbit which may have been sculpted by interaction with the companion star, Gliese 15 B.[3][4] As of 2020, Gliese 15 Ac is the longest-period sub-Jovian planet discovered by radial velocity.[3][5]
