Planet ekstragalaksi

Planet ekstragalaksi, juga dikenal sebagai sebuah eksoplanet ekstragalaksi, adalah sebuah planet terikat bintang atau planet pengembara yang terletak diluar Galaksi Bima Sakti. Karena jarak yang sangat jauh, planet-planet tersebut akan sangat sulit dideteksi secara langsung. Namun, bukti tidak langsung menunjukkan bahwa planet semacam itu mungkin ada.^[1]^[2]^[3]
