NASA scientists perceive Jupiter, Uranus, Saturn, Neptune, and the Earth-Moon as additional destinations.
Uranus and Neptune are ice giant. Voyager 2 is the only spacecraft to have visited them.
Jupiter is the grandest planet. Jupiter has 79 moons, the most of any planet in the solar system. Nine spacecrafts have visited Jupiter. Seven flew by and two have orbited the gas giant. Juno, the most recent arrived at Jupiter in 2016. Jupiter and Saturn are gas giant.
Saturn is the second largest planet in our solar system. Several missions have already visited Saturn: Pioneer 11, Voyager 1 and 2 flew by, but Cassini orbited Saturn 294 times from 2004 to 2017. Saturn has 53 known moons with an additional 9 moons awaiting confirmation of their discovery—this is a total of 62 moons. Some of Saturn's moons have conditions that might support life. Saturn has the most spectacular ring system with seven rings and several gaps and divisions between them.
So far, the Earth-Moon had 24 human visitors, 12 moonwalkers and over 100 robot visits. The Moon is a rocky, solid-surface body with much of its surface cratered and pitted from impacts. Humans can stand on it.
