An exoplanet or extrasolar planet is a planet that orbits a star other than our own planet's Sun. The first scientific detection of an exoplanet was in 1988. However, the first confirmed detection came in 1992; since then, and as of 22 February 2017, there have been 3,583 exoplanets in 2,688 planetary systems and 603 multiple planetary systems confirmed.
