HD 114386 b is an exoplanet orbiting the star HD 114386. The planet orbits the star in a rather eccentric orbit. Mean distance from the star is 1.62 AU, somewhat more than distance between Mars and the Sun. At periastron, the planet comes almost as close as Earth orbits the Sun, and at apoastron, the distance is twice as much.[1]
