The only spacecraft to have visited Neptune is the space probe Voyager 2, which flew by Neptune in August 1989.
To the best of our knowledge, no satellites or robots have directly explored the planet Haumea. Haumea is a dwarf planet located in the Kuiper Belt beyond Neptune, and its distance from Earth makes it challenging to send a mission there. Most of our knowledge about Haumea comes from observations made by telescopes on Earth.
There have been no dedicated missions to explore Uranus with satellites or robots. The only spacecraft to have conducted a close flyby of Uranus was Voyager 2 in 1986.
The Cassini spacecraft, a joint mission by NASA, ESA, and the Italian Space Agency, explored Saturn from 2004 to 2017. It provided detailed information about Saturn's rings, moons, and atmosphere before intentionally plunging into the planet to end its mission.
Dead. Neptune is almost all storms and extemely high winds.
Now that Pluto has been downgraded to a dwarf planet, Neptune is the most distant planet from the Sun. It takes 164.79 Earth years for Neptune to circle the Sun, so one Earth year would be about 1/165 of a Neptune year (the time it takes Neptune to circle the Sun).
Only Voyager 2.

Neptune's largest moon, Triton, was visited by the Voyager 2 spacecraft in 1989. There are no other dedicated "satellite robots" sent to Neptune's other moons as of current knowledge.

30 years(in Apollo spacecrafts)
It depends, if it was made for harbouring people then yes they do contain people- nowadays more and more spacecrafts are being made for people. Such as Virgins ambition for Virgin Galactic. However there are also spacecrafts that are sent to Jupiter and Uranus and Neptune that don't contain people, as it is either is: 1) Too far and life is too short to spend 10 years in a spaceshuttle. 2) Too dangerous as the spacecraft might explode under high pressure. Hope i helped!

Neptune are 164.79 years compared to earth
he explored eastern south America

Neptune was the farthest for 20 years. then pluto came.
It took twelve years to get from earth to neptune.
