Neptune was not discovered by spacecraft.
The existence of Neptune was predicted on paper by Frenchman Urbain Le Verrier and Englishman John Couch Adams.
It was later discovered by telescope by Johann Gottfried Galle in 1846.
Voyager 2 did a flyby of Neptune in 1989 and sent images back to Earth. But it did not discover it.

Only one space probe has ever visited Neptune, and that's Voyager 2, which flew past in 1989.
