It is the only program that visited all four outer planets. A total of nine spacecraft have been launched on missions that involve visits to the outer planets; all nine missions involve encounters with Jupiter, with four spacecraft also visiting Saturn. One spacecraft, Voyager 2, also visited Uranus and Neptune.
Planets. Counter-Earth, a planet situated on the other side of the Sun from that of the Earth. Fifth planet (hypothetical), historical speculation about a planet between the orbits of Mars and Jupiter. Phaeton, a planet situated between the orbits of Mars and Jupiter whose destruction supposedly led to the formation of the asteroid belt.

Voyage to the Outer Planets was an early multimedia experiment, first presented in 1973, combining Omnimax film, 70 mm film and planetarium special effects. The special effects and stills on standard and zoom equipped slide projectors were provided by the Reuben H. Fleet Space Theater, and their Spitz Space Transit Simulator (STS).
Nice model. The Nice ( / ˈniːs /) model is a scenario for the dynamical evolution of the Solar System. It is named for the location of the Côte d'Azur Observatory —where it was initially developed in 2005—in Nice, France. [1] [2] [3] It proposes the migration of the giant planets from an initial compact configuration into their present ...
Grand Tour program. The Grand Tour is a NASA program that would have sent two groups of robotic probes to all the planets of the outer Solar System. It called for four spacecraft, two of which would visit Jupiter, Saturn, and Pluto, while the other two would visit Jupiter, Uranus, and Neptune. The enormous cost of the project, around $1 billion ...
v. t. e. The Kuiper belt ( / ˈkaɪpər / KY-pər) [1] is a circumstellar disc in the outer Solar System, extending from the orbit of Neptune at 30 astronomical units (AU) to approximately 50 AU from the Sun. [2] It is similar to the asteroid belt, but is far larger—20 times as wide and 20–200 times as massive. [3] [4] Like the asteroid ...
Extraterrestrial atmosphere. Major features of the Solar System (not to scale) Graphs of escape velocity against surface temperature of some Solar System objects showing which gases are retained. The objects are drawn to scale, and their data points are at the black dots in the middle. The study of extraterrestrial atmospheres is an active ...
