Un '''exoplaneta''' o '''planeta extrasolar''' es un planeta situat en defòra del [[Sistèma Solar]]. La primièra pròva d'un exoplaneta foguèt notada en 1917, mas foguèt pas reconeguda coma tala. Pasmens, la primièra deteccion scientifica d'un exoplaneta se faguèt en 1988, e mai que foguèsse pas confirmada coma essent un exoplaneta abans 2012. En 2018, i a aperaquí 3900 exoplanetas confirmada dins 2900 sistèmas planetaris descobèrts.
