Ganymede, the largest moon in the solar system, orbits Jupiter and is larger than Mercury and Pluto, slightly smaller than Mars. Discovered by Galileo in 1610, it would be classified as a planet if it orbited the Sun. Ganymede has a unique magnetic field, an iron-rich core, and a potential ocean beneath its surface. It takes about 7 days to orbit Jupiter and is approximately 4.5 billion years old. Its internal structure includes layers of ice and rock, with a solid iron core.
