Ganymede appears to get several ocean levels, stacked up with levels of ice in between them. The highest amount of ice will be the crust, which could be about 150 kilometers (about ninety miles) thick. The bottom ocean amount could possibly be 800 kilometers (about 500 miles) under that, just above the very first layer on the moon’s rocky interior.

Like Frankenstein’s monster, Miranda seems like it had been pieced alongside one another from sections that didn’t really merge thoroughly. Miranda’s huge fault canyons are approximately 12 situations as deep as being the Grand Canyon.
Callisto may be the minimum dense of Jupiter’s moons. It has The great fortune of orbiting one.eight million kilometers from your planet, further than Jupiter’s extreme radiation belts. For the reason that Jupiter’s gravitational area is weaker at this distance, Callisto also experiences considerably get more info less tidal friction than its companion moons.
This compact moon of Neptune is on the collision study course Using the planet. At some point, astronomers say, the closely cratered Larissa will tumble in to the environment of its guardian World or be ripped by gravity.

Crater-protected Mimas is the smallest and innermost of Saturn’s main moons. Mimas will not be pretty sufficiently big to hold a round shape and its minimal density indicates that it is made up Practically totally of drinking water ice.
With volcanoes, frozen oceans, and methane seas, moons tend to be Substantially over balls of rock circling a physique aside from the Sunlight.
NASA stories that Callisto is the 3rd major satellite during the photo voltaic program and around the scale of Mercury. Pictured here in color, NASA details out that its several markings demonstrate a turbulent heritage of collisions with Place objects. In fact, Callisto is understood to be essentially the most greatly cratered object in our photo voltaic system.
Saturn and Jupiter will be the planets with the greatest range of moons, with dozens of satellites orbiting Just about every of the two giant planets.
