Main focus would be to map the gravitational fields in deep space, including the Outer Solar System (up to 50 AU) proposed [15] [16] OSS ESA/NASA: flyby proposed [17] Triton Hopper: NASA: rocket-powered "hopper" An NIAC study of a mission to Neptune with the goal of landing, and flying from site to site, on Neptune's moon Triton. proposed [18 ...
This is a list of all spacecraft landings on other planets and bodies in the Solar System, including soft landings and both intended and unintended hard impacts.The list includes orbiters that were intentionally crashed, but not orbiters which later crashed in an unplanned manner due to orbital decay.
Montage of planets and some moons that the two Voyager spacecraft have visited and studied. 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.
Would've focused on Neptune and its largest moon, Triton, addressing questions raised by Voyager 2's 1989 flyby [134] and would've provided insights into the formation and evolution of ice giants.

The bright S/2002 N5 moon is 14 miles (23 kilometers) in diameter and takes nearly nine years to complete an orbit of Neptune, while faint S/2021 N1 is about 8.7 miles (14 kilometers) across and ...
Neptune 25 August 1989 4389 days (12 yr, 6 days) Voyager 2 flew by Neptune and was the first spacecraft to visit it. Voyager 1: Jupiter 5 September 1977 5 March 1979 547 days (1 yr, 6 mo, 1 d) Voyager 1 flew by Jupiter and returned the first detailed images.

This is a list of space probes that have left Earth orbit (or were launched with that intention but failed), organized by their planned destination. It includes planetary probes, solar probes, and probes to asteroids and comets, but excludes lunar missions, which are listed separately at List of lunar probes and List of Apollo missions.
Timelapse of Voyager 2 approaching Jupiter. The plains of Pluto, as seen by New Horizons after its nearly 10-year voyage. Remotely guided space probes have flown by all of the observed planets of the Solar System from Mercury to Neptune, with the New Horizons probe having flown by the dwarf planet Pluto and the Dawn spacecraft currently orbiting the dwarf planet Ceres.
