Sun Ra and his Solar Arkestra Visits Planet Earth Sun Ra and his Solar Arkestra Visits Planet Earth Sun Ra and his Solar Arkestra Visits Planet Earth is a jazz album by the American musician Sun Ra and his Solar Arkestra. Recorded between late 1956 and 1958, the album was originally released on Ra's own Saturn label in 1966, and has since been reissued on CD by Evidence in 1992.
