What was Galileo’s greatest contribution?

discovery of the four most massive moons of Jupiter
, now known as the Galilean moons: Io, Ganymede, Europa and Callisto. When NASA sent a mission to Jupiter in the 1990s, it was called Galileo in honor of the famed astronomer.

that the Sun – not the Earth – was the center of the Universe, as was commonly believed at the time. Galileo’s work laid the foundation for today’s modern space probes and telescopes.

Who discovered Earth?
Eratosthenes
then measured the angle of a shadow cast by a stick at noon on the summer solstice in Alexandria, and found it made an angle of about 7.2 degrees, or about 1/50 of a complete circle. He realized that if he knew the distance from Alexandria to Syene, he could easily calculate the circumference of Earth.
