Gliese 414 Ab
Sub-Neptune exoplanet orbiting Gliese 414 A / From Wikipedia, the free encyclopedia
Gliese 414 Ab, also known as GJ 414 Ab, is a sub-Neptune exoplanet orbiting Gliese 414 A, an orange dwarf located 39 light-years from Earth, in the constellation Ursa Major.[4][note 1] It is at least 7.6 times more massive than the Earth and is 3 times larger, having a diameter of 37600 km.[5] It orbits its host star at a distance of 0.24 astronomical units (36,000,000 km), completing one revolution every 51 days.[5] The distance of Gliese 414 A b from its star makes it to be located in the inner part of the optmistic habitable zone, and the planet has a equilibrium temperature of 35.5 °C.[5]
