Gliese 414 Ac, or GJ 414 Ac, is an exoplanet orbiting Gliese 414 A, a K-type main-sequence star located 39 light-years from Earth, in the constellation Ursa Major. It is classified as a super-Neptune exoplanet, being at least 54 times more massive than the Earth and about 8.5 times larger. Gliese 414 Ac orbits its parent star at a distance of 1.4 astronomical units and completes one revolution around it every 2 years and 20 days. It is one of the two planets orbiting Gliese 414 A, the other is Gliese 414 Ab, a sub-Neptune.
