Italian astronomer Galileo Galilei drew Neptune twice in his notebook as he discovered the planet through the telescope when it was in conjunction with Jupiter.
We have found that Galileo observed the planet Neptune on 28 December 1612 and 28 January 1613. The latter observation may be of astrometric value, and differs by 1 arc min from the predicted position of Neptune. Galileo also detected the motion of Neptune.
Unlike Uranus and Ceres, Neptune was not discovered by accident. It was proposed that a planet beyond Uranus could account for irregularities in Uranus’ orbit. Independently, two astronomers, John Couch Adams in England and Urbain-Jean-Joseph Le Verrier in France, calculated the position of this yet unknown planet.

Who officially discovered Neptune?
To Galileo’s surprise, Saturn wasn’t just one planet, but three! A big middle planet with a small planet or moon on each side, and the three were almost touching. Galileo drew it like this: Other astronomers, whose telescopes were not as good as Galileo’s, saw a single oval planet.
Was Neptune found accidentally?
Today, both men – and Galle, who was the first to knowingly see the new planet through a telescope – are credited with the discovery. Ironically, as it turns out, both Le Verrier and Adams had been very lucky. Their predictions indicated Neptune’s distance correctly around 1840-1850.
