HD 114386 b is anexoplanet orbiting thestarHD 114386. The planet orbits the star in a rathereccentric orbit. Mean distance from the star is 1.62AU, somewhat more than distance betweenMars and the Sun. Atperiastron, the planet comes almost as close asEarth orbits the Sun, and atapoastron, the distance is twice as much.[1]
