HD 114386 is a 9th magnitude star in the constellation of Centaurus. It is an orange dwarf, and rather dim compared to our Sun. To see it, one needs a telescope or good binoculars.

In 2004, the Geneva Extrasolar Planet Search Team announced the discovery of an extrasolar planet orbiting the star.

HD 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. At periapsis, the planet comes almost as close as Earth orbits the Sun, and at apoapsis the distance is twice as much.
