Whether it’s the most interesting, the most beautiful, or the strangest one for you, which is, in your opinion, the best moon in the Solar System?
Could it be the Earth’s own moon, being so large in comparison to the size of our Planet? Perhaps little Phobos and Deimos of Mars? The Galilean moons of Jupiter? Titan, Saturn’s largest moon and the only one in the Solar System with a thick atmosphere? Farther out, you have the moons of Uranus, Neptune, and Pluto…
Galilean moons of course.
Everyone, including Galileo, thought that Earth is in the center of the universe and literally everything in the sky rotates around it. So he build a telescope, looked at the Jupiter and saw some dots. He looked later and the dots were in different configuration. After just couple of days he knew the dots orbit Jupiter. And suddenly the central believe of humanity was out the window. Not everything orbits Earth. We are not in the center of the universe. And the proof was right there, everyone could see it with their own eyes. Today it would be like proving we live in a simulation in way, that everyone can verify (but you know, without drugs and lasers). Every time I see the Galilean moons I think about it. Probably the greatest revolution in the human understanding of the universe, right there, for everyone to see.
