An extrasolar planet or exoplanet is a planet that orbits around any star other than the Sun and, therefore, is part of planetary systems other than our own. Although their existence had been suspected for a long time, they did not begin to be discovered until the 1990s, thanks to improvements in detection techniques. The first extrasolar planet discovered orbiting a main sequence star was 51 Pegasi b, discovered in 1995 by Michel Mayor and Didier Queloz of the Geneva Observatory. This planet has a mass comparable to that of Jupiter. Since then more than a hundred planets have been discovered by different international groups.
