| Launched in the late summer of 1977 within weeks of each other, the two probes made for the outer planets Saturn and Jupiter. |
| Now, however, they appear to be the most effective way to reach the outer planets of our solar system. |
| The three outer planets were Jupiter-class gas giants, with an asteroid belt between the first gas giant and the second gas giant. |
| One of four gas giant outer planets, Saturn is the second most massive planet in the solar system. |
| Further afield there are the starkly beautiful pictures taken by Voyager, of a ringed Saturn and the outer planets, Uranus and Neptune. |
| Later cosmogonists discarded this theory mostly because it did not account for the greater angular momentum of the outer planets. |
