None.
No space missions have landed on Neptune or flown by it. The only spacecraft that has visited Neptune is Voyager 2, which conducted a flyby of the planet in 1989. There are no current plans for future missions to Neptune.
Neptune has not had any space exploration missions. However, it has been visited by the Voyager 2 spacecraft, which flew by the planet in 1989 and provided valuable information about its atmosphere, moons, and rings. There are no current plans for future missions to explore Neptune directly.
Only one space probe went to or flew by Neptune which was Voyager 2.
Yes, Voyager II has. (Voyager II is an unmanned space probe).

There have been no astronauts that have gone to Neptune. Nor is there any space exploration projects or programs called Neptune that I am aware of.
None of the users gave a reliable answer. Please research.But as far as I know, there is no new missions to Neptune?
We should send space probe just like New Horizons Spacecraft to Eris. So we can launch this spacecraft in 2015 to make Jupiter, Saturn, and Neptune flybys then to Eris.
Only one space probe has ever visited Neptune, and that's Voyager 2, which flew past in 1989. However, I suppose you could add the Hubble Space Telescope to the list too, since even though it orbits Earth it is a space mission and has taken photos of Neptune that are far clearer than any we can obtain from the ground - nothing approaching the quality of Voyager 2's pictures, though.
The answer depends on "before what".
