Callisto Facts. 1  Callisto is the second largest moon orbiting Jupiter and the third largest moon in the solar system. 2  It has a diameter of 2,985 miles (4,800 km), which is only 1% smaller than the planet Mercury.3  Callisto is the 8th moon in distance from Jupiter and takes 17 days to make one complete orbit of the planet.he highest daytime temperature on Callisto is around -108C (-162 F). At night temperatures can reach an even more chilly -193C (-315 F). Microbial life may exist in the ocean underneath Callisto's surface although the conditions may be less favorable than on Europa or Ganymede.
