Title:
Ganymede: The Largest Moon in the Solar System Title Ganymede: The Largest Moon in the Solar System Title
Explanation:
If Ganymede orbited the Sun, it would be considered a planet. The reason is that Jupiter [ http://galileo.jpl.…]'s moon Ganymede [ http://www.seds.org…] is not only the largest moon in the Solar System [ http://www.seds.org…], it is larger than planets Mercury [ http://www.seds.org…] and Pluto [ http://dosxx.colora…]. The robot spacecraft Galileo [ http://www.jpl.nasa…] currently orbiting Jupiter [ http://www.seds.org…] has been able to zoom by Ganymede [ http://www.solarvie…] several times and snap many close-up pictures. Ganymede, shown above [ http://photojournal…] in its natural colors, sports a large oval dark region known as Galileo Regio [ http://www.jpl.nasa…]. In general, the dark regions on Ganymede [ http://sse.jpl.nasa…] are heavily cratered, implying they are very old, while the light regions are younger and dominated by unusual grooves [ http://antwrp.gsfc.…]. The origin of the grooves is still under investigation [ http://adsabs.harva…]. Explanation If Ganymede orbited the Sun, it would be considered a planet.
