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. In keeping with many Saturn releases, one side features cuts from the arkestra c.1958, whilst the other side comes from the 1956 sessions originally intended for "Sound of Joy" but still unreleased in 1966. All songs by Sun Ra
Jupiter in the Solar System for which this is true. Jupiter has been called the Solar System's vacuum cleaner, because of its immense gravity well and location near the inner Solar System. It receives the most frequent comet impacts of the Solar System's planets. It was thought that the planet served to partially shield the inner system from cometary bombardment. However, recent computer simulations suggest that Jupiter does not cause a net decrease in the number of comets that pass through the inner Solar System, as its gravity perturbs their orbits inward roughly as often as it accretes or ejects them.
