Voyager 2 flew by Neptune in 1989, coming within 30,000km of the planet.
Voyager 2, which flew by the giant planet in 1989.
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.
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.
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.
No spacecraft has visited all the planets.
Voyager 2 is the only spacecraft to currently visit Neptune, passing 3,000 miles from the planet on August 25, 1989.
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.
Depends on whether you say Pluto is a planet or not. If you say it isn't, then there are no planets that haven't been visited by a spacecraft. If you say it is, then there is one that hasn't been visited yet, but one is on the way.
There are no man-made satellites or robots of Neptune. The space probe "Voyager 2" flew past Neptune, in 1989.
Neptune was the last planet to be visited by the space probe called Voyager II. It was launched by NASA and the probed flew past the planet in 1989.
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.
