Voyager 2, which flew by the giant planet 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.
Voyager 1 never visited Neptune. Voyager 2 has. Voyager 2 is currently the only scientific instrument to do a fly-by of Neptune.
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.
Voyager 1 and 2 explored the outer planets of our solar system, primarily focusing on Jupiter and Saturn. Voyager 1 conducted a flyby of Jupiter in 1979 and Saturn in 1980, while Voyager 2 visited Jupiter in 1979, Saturn in 1981, Uranus in 1986, and Neptune in 1989. These missions provided invaluable data about the planets, their moons, and ring systems.

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.
Voyager 2 flew by Saturn in 1981, the second planet visited by the Voyager program after Jupiter. It provided valuable data and images of Saturn, its rings, and its moons, enhancing our understanding of the planet and its system.
Voyager 2 flew by Neptune in 1989, coming within 30,000km of the planet.
Voyager 1 never visited Neptune. Voyager 2 has. Voyager 2 is currently the only scientific instrument to do a fly-by of Neptune.
Voyager 2 is the only spacecraft to currently visit Neptune, passing 3,000 miles from the planet on August 25, 1989.
Voyager 2 reached that planet in January 1986, about 81/2 years after it was launched in August 1977.
