Detailed explanation-1: -The discovery of these moons around Jupiter showed that celestial bodies could orbit around objects other than the Earth. Since Galileo’s time many more moons of Jupiter have been discovered, and at the time of writing there are 79 known moons of Jupiter.
Detailed explanation-2: -This opposed the view of Geocentrism which stated that the earth was the center of the solar system. Galilei corroborated Heliocentrism when he observed through a telescope that moons were revolving around Jupiter. This meant that earth could not be the center of motion.
Detailed explanation-3: -The discovery, along with his discovery of three other large moons around Jupiter, was the first time a moon was discovered orbiting a planet other than Earth. The discovery eventually led to the understanding that planets in our solar system orbit the Sun, instead of our solar system revolving around Earth.
Detailed explanation-4: -With this discovery and his observations of the phases of Venus later that same year, Galileo gave us proof of a heliocentric universe. Earth was not fixed at the center of the cosmos, but rather moved around the Sun just as other planets did.
