Jupiter's Callisto is the third largest moon in our solar system and is almost the size of Mercury, but only about a third of its mass. Callisto was discovered on 7 January 1610 by Galileo Galilei. The discovery, along with three other Jovian moons, was the first time a moon was discovered orbiting a planet other than Earth. The discovery of the four Galilean satellites eventually led to the understanding that planets in our solar system orbit the sun, instead of our solar system revolving around Earth. Callisto is the outermost of the Galilean satellites, and orbits beyond Jupiter's main radiation belts. Callisto is the most heavily cratered object in our solar system. With its icy surface age of about 4 billion years, Callisto has the oldest landscape in the solar system. It is thought to be a long dead world, with hardly any geologic activity on its surface. But it appears that Callisto, like another of Jupiter's moons Europa, may have an underground liquid ocean and at least some of the basic ingredients for life. In 2022 the European Space Agency is planning to launch the Jupiter Icy Moons Explorer (JUICE), which will study Ganymede, Europa and Callisto, and their potential for containing life.
