Moons are natural satellites that orbit around planets, much like how the Earth’s moon orbits our planet. They come in various sizes and shapes, and some are rocky while others are icy. Moons can be found in our solar system, with notable examples like Jupiter's moon Europa and Saturn's moon Titan, each having unique features and potential for exploration. The study of moons helps scientists understand more about the formation of planets and the history of our solar system. Some moons, like Earth's moon, influence tides and have a significant impact on life on Earth. Exploring these celestial bodies can reveal secrets about the universe.
