Ganymede. It's bigger than Mercury, has a liquid iron core and is the only moon in the Solar System with its own magnetic field. The terrain is varied, but there are broadly two different types: heavily-cratered dark regions (evidence of great age) and brighter regions showing patterns of ridges and grooves for thousands of miles, suggesting later geological activity, but nonetheless ancient. ©Mona Evans,"Jupiter's Galilean Moons" www.bellaonline.c...
