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. Jupiter has more than 60 known moons including four—Io, Europa, Ganymede and Callisto—that were discovered in 1610 when Galileo was the first to view it through a telescope. They can be seen easily through binoculars or a small telescope. Ganymede 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.
