Galileo did not discover Neptune. Neptune was officially discovered on September 23, 1846 by astronomers Johann Galle and Heinrich d'Arrest, based on calculations by Urbain Le Verrier and John Couch Adams.
The telescope, which was first built by Hans Lippershey in 1608. Galileo built a telescope in 1609 and discovered Saturn with it in 1610.
He discovered it on the moon.
At his house
Uranus was not discovered by Galileo Galilei. Some of the things that Galileo did discover was that there were four moons around Jupiter and that everything falls at the same speed.

Only Voyager 2 flew by Neptune. Voyager 1, Pioneer and Galileo did not.
Galileo did record its position but, because Neptune was just entering its retrograde phase, he did not see its orbital motion an so thought it was a star.It was properly identified by Johann Gottfried Galle in 1846.
he used a telescope to discover Neptune
No, Venus was already known of in Galileo's time.
nope

Edwin Hubble did not discover Neptune. Galileo's drawings show that he first observed Neptune on December 28, 1612, and again on January 27, 1613. On both occasions, Galileo mistook Neptune for a fixed star when it appeared very close in conjunction to Jupiter in the night sky, hence, he is not credited with Neptune's discovery. Neptune was discovered due to the anomalies it caused i Uranus' orbit. There is a small dispute over who discovered Neptune. An international consensus emerged that two astronomers, Urbain Le Verrier and John Couch Adams, jointly deserved credit. See the link for more information. The law of Gravitation predicted the existence of planets beyond Uranus Observations in the orbit of Uranus led to the discovery of planet Neptune. It was discovered in the nineteenth century.
Galileo's greatest discovery was the discovery of jupiter's moons and rings.
In astronomy, he used a telescope.
