The moons of Jupiter are called Galilean moons because Galileo Galilei discovered them. These moons helped prove the theory of a heliocentric model (the sun is the center of t â¦ he solar system) for the universe and challenged the geocentric theory (Earth-centered) views of the Church.
And until 1892, that was it! Just four moons, not so hard. The Galilean moons are still the largest, and probably the coolest, of Jupiter's moons. Io is the most volcanically active place in the solar system, with 250-mile-high lava spurts possibly fed by an ocean of molten rock.
