Distinguishing features Jupiter has an interesting feature called the Great Red Spot, a huge storm of swirling gas that has lasted for hundreds of years. Three Earths would fit within the boundaries of the Great Red Spot, which appears brownish-red. Ganymede, a Galilean moon, is the largest moon in our solar system (larger than even the planet Mercury), and is the first moon known to have its own magnetic field.
