Options:

Answer: Galileo Galilei

Jupiter’s four largest moons Io, Callisto, Europa and Ganymede are known as the Galilean moons because the first recorded observation of the moons was by Italian astronomer Galileo Galilei in 1610. The Galilean moons are fascinating worlds. Ganymede, for example, is the largest moon in the Solar System.
