Galileo discovered the 4 moons of jupiter through a telescope which he never invented but was the first to use.
Jupiter is the fifth planet from the sun, and has the most moons out of all the planets in our solar system. Some of the planets (Mercury and Venus) have no moons, while Jupiter has a whopping 63! These are just the known moons - so thereâs always a chance that more will be discovered! The four largest of Jupiterâs moons are known as the Galilean moons: Callisto, Europa, Ganymede, and Io. They were discovered by Galileo Galilei, an Italian astronomer, in 1610. Io is the closest moon to Jupiter, and is covered in many volcanoes.
