Out of the Silent Planet is the second studio album by the American rock band King's X, released in 1988. The title of the album comes from that of a book by C. S. Lewis, an author favored by band members Ty Tabor and Jerry Gaskill. "Out of the Silent Planet" is also the title of the first track from the follow-up album Gretchen Goes to Nebraska. The cover art features the skyline of Houston with the southern outline of the state of Texas. The album received widespread acclaim from music contemporaries.
