star in the constellation ofCentaurus . It is an orange dwarf, and rather dim compared to ourSun . To see it, one needs atelescope or goodbinoculars .In 2004, the
Geneva Extrasolar Planet Search Team announced the discovery of anextrasolar planet orbiting the star.HD 114386 b

mass = >1.24 "M"JHD 114386 b is a
planet orbiting the star. Its minimum mass is almost exactly the same as Jupiter. However, it is likely that the planet is actually more massive, but not by much.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. Atperiapsis , the planet comes almost as close asEarth orbits the Sun, and atapoapsis the distance is twice as much.References
