Voyager 2, which flew by the giant planet in 1989.
As of 2011, only one spacecraft has passed relatively close to Neptune. The Voyager 2 probe visited Neptune in 1989, having previously passed Jupiter, Saturn, and Uranus. Voyager 2 took the first close-up photos of the Neptunian moon Triton, and discovered five inner moons: Naiad, Thalassa, Despina, Galatea and Proteus.
Only one through 2009. The Voyager 2 probe visited Neptune in 1989, having previously passed Jupiter, Saturn, and Uranus. Voyager 2 took the first close-up photos of the Neptunian moon Triton and discovered 5 new inner moons.
Not yet. And there never will be a spacecraft landing on Neptune. The reason being, because Neptune is a gas giant, it has no solid surface for a spacecraft to land on. Neptune is also freezing cold. Electronic equipment such as a spacecraft would freeze up and malfunction in its atmosphere and most likely end up being consumed by the exposed molten ammonia core.
It may be possible in the future, but today we are not able to travel that far.
Never have. It is beyond the sun and we don't have the space techo to get there yet. I don't think there has even in a probe to the planet.
Voyager 2 flew by Neptune in 1989, coming within 30,000km of the planet.
Just one.

The most successful space probe launched to Neptune was Voyager 2. It made its closest approach to Neptune in 1989, providing valuable data and images of the planet and its moons. Voyager 2 remains the only spacecraft to have visited Neptune.
Yes, the Voyager 2 probe visited all four gas giant planets; Jupiter, Saturn, Uranus and Neptune. It flew by Neptune in 1989.

No spacecraft from Earth has ever landed on Neptune.
Yes, but they have not landed.

Nobody. It is impossible to walk on Neptune as there is no solid surface. The only object where people have walked other than Earth is the moon.
A spacecraft left earth in late 1957 and returned in early 1958. Other than human spacecraft, no alien space craft has ever left or come to visit our planet, that we know of. It is possible some alien space craft may have visited earth millions of years ago. It is highly unlikely any craft has done so within the past few centuries.
