Ganymede

How did it form? Ganymede formed 4.6 billion years ago after Jupiter was formed. It is thought to have formed by accretion from the gas and dust that was around Jupiter after it was created.

What are the physical characteristics? The physical characteristics are cratered, with dark and light regions. The more cratered areas are normally in the darker regions. It also has a plain, which is called the Galileo Regio.

Is there potential for life? There may be potential for life below the surface, because below the surface of Ganymede is a saltwater ocean. Although the saltwater ocean is no close to the surface, like Europa, it is 124 miles below the surface.

Does it have a heat source? Its core is hot liquid iron which generates a magnetic field. This magnetic field is inside the magnetosphere of Jupiter. Which is where charged particles are deflected.

What’s the atmosphere like? The atmosphere of Ganymede is thin oxygen. It is not enough oxygen to support life though.

How geologically active is it? It is not geologically active.

What’s its composition? Equal parts rocky material and water (in the form of ice). The makeup of the rocky material on Ganymede is unknown, but is suspected to be iron oxide and H chondrites. It is made up of dark and light rock and the dark rock is suspected to be silicate rock.
