Jupiter's Moons Thebe, Amalthea, and Metis

Jupiter's Moons Thebe, Amalthea, and Metis

Explanation:
|
The robot spacecraft Galileo [ http://eis.jpl.nasa…] in orbit around Jupiter [ http://www.seds.org…] has recently photographed the inner moons of Jupiter in greater detail than ever before. These pictures [ http://www2.jpl.nas…] of Thebe [ http://www.solarvie…], Amalthea [ http://www.solarvie…], and Metis [ http://www.solarvie…] are shown to scale, and reveal details as small as three kilometers across. Amalthea [ http://www.seds.org…], by contrast, has a total length of about 200 kilometers. The moons [ http://antwrp.gsfc.…] are composed mostly of ice, are much smaller than Jupiter's more famous Galilean satellites [ http://www.jpl.nasa…] (Io [ http://www.seds.org…], Europa [ http://www.seds.org…], Ganymede [ http://www.seds.org…], and Callisto [ http://www.seds.org…]), and orbit between Io and Jupiter's rings [ http://antwrp.gsfc.…]. Thebe appears dominated by a huge impact crater [ http://gdcinfo.agg.…] 40 kilometers across. Astronomers are uncertain of the origin of the unusual white gash at the bottom of Amalthea [ http://www.jpl.nasa…].
