Any planet that navigates around a star, other than the Sun, is an exoplanet.

Many planets (over 200) have been discovered in the nineties that don't go around our Sun. They are exoplanets.

An exoplanet (exo-planet), is an extra-solar (outside of our solar system) planet orbiting a star, other than the Sun, within our Milky Way galaxy.

The Kepler Telescope mission has discovered 4,000+ confirmed exoplanets in all, as of February 2015.
