Un planeta exoplaneta es un planeta fuera del Sistema Solar. La primera confirmación de detección ocurrió en 1992. Al 1 de octubre de 2022, hay 5197 exoplanetas confirmados en 3833 sistemas planetarios, con 840 sistemas que tienen más de un planeta. Las afirmaciones de detecciones de exoplanetas se han hecho desde el siglo XIX. Algunos de los primeros involucran a la estrella binaria 70 Ophiuchi. En 1855, William Stephen Jacob, del Observatorio de Madrás de la Compañía de las Indias Orientales, informó que las anomalías orbitales hacían «altamente probable» que hubiera un «cuerpo planetario» en este sistema.

An exoplanet planet is a planet outside the Solar System. The first confirmation of detection occurred in 1992. As of 1 October 2022, there are 5,197 confirmed exoplanets in 3,833 planetary systems, with 840 systems having more than one planet. Claims of exoplanet detections have been made since the nineteenth century. Some of the earliest involve the binary star 70 Ophiuchi. In 1855 William Stephen Jacob at the East India Company’s Madras Observatory reported that orbital anomalies made it “highly probable” that there was a “planetary body” in this system.
