Quizplus · Accepted Answer

The first extrasolar planets, also known as exoplanets, were discovered in 1995 by Swiss astronomers Michel Mayor and Didier Queloz. They detected a planet orbiting the star 51 Pegasi using the radial velocity method, which measures variations in the star's spectrum caused by the gravitational pull of an orbiting planet. This discovery revolutionized our understanding of planetary systems beyond our own solar system.
