Ganymede

Card 1 of 2

A Moon of Jupiter

The image is of Ganymede, one of Jupiter's moons. It appears as a spherical body, showcasing a surface with contrasting dark and light regions. The dark areas are heavily cratered, indicating ancient terrain, while the light regions are grooved and ridged, suggesting more recent geological activity. Subtle shades of gray, brown, and white dominate the surface. There are visible patterns of crisscrossing lines and large, irregular patches of varying textures, highlighting the moon's complex geology.

Ganymede may have an ocean of liquid water deep in the subsurface.

Gravity

Ganymede’s gravity is 0.15 times the gravity of Earth.

Composition

Rock & Ice

The image is a cross-sectional diagram depicting the interior structure of Ganymede, Jupiter's largest moon. At the center is the iron core, represented as a small, textured, reddish-brown circle. Surrounding the iron core is a larger layer labeled the rocky mantle, shown in a dark gray color. Enveloping the rocky mantle is the salty ocean layer, depicted in a bright blue hue. Beyond this layer is the ice mantle, which is a slightly lighter blue. The outermost section is labeled the ice crust, presented in a very light blue shade with a thin, defined line. Each layer is labeled clearly. Below the diagram, text reads "Model of the interior of Ganymede."
