Neptune was discovered by Urbain Le Verrier, John Couch Adams, and Johann Galle
Johann Gottfried Galle did not discover a planet himself. He was the astronomer who, in collaboration with Urbain Le Verrier, first observed the planet Neptune in 1846 based on Le Verrier's calculations.
For the first time ever, a mathematical rather than an observational method was used to discover a planet.
First, the name is John Couch Adams. He was the first to predict the presence of Neptune, but he didn't actually discover it. That was done by astronomers with a telescope using predictions from John Couch Adams an also from Le Verrier.
"Neptune" was discovered on September 23, 1846.
The first planet to be discovered using observed gravitational anomalies was Neptune. Its existence was predicted mathematically based on irregularities in the orbit of Uranus, which led astronomers to search for and discover Neptune in 1846.

No humans have visited the planet Neptune.

In our Solar System, the closest planet to the Sun is Mercury, and the furthest is Neptune.
Neither. Neptune is the 8th planet from the Sun.
The first planet orbiting the sun is Mercury, and the last planet is Neptune. Mercury is the closest planet to the sun, while Neptune is the farthest.
The last planet to discover during the 20th century was Pluto. But it's a dwarft planet so it should maybe be Neptune.
