Title:
Jupiter's Moon Amalthea
Explanation:
Amalthea is Jupiter [ http://antwrp.gsfc.…]'s fifth largest moon, much smaller than the four Galilean [ http://bang.lanl.go…] satellites Io [ http://antwrp.gsfc.…], Europa [ http://antwrp.gsfc.…], Ganymede [ http://antwrp.gsfc.…], and Callisto [ http://antwrp.gsfc.…]. The orbit of Amalthea [ http://seds.lpl.ari…] is inside of these moons, and with its long axis always pointing toward Jupiter [ http://antwrp.gsfc.…]. It's dark surface color is probably due to sulfur being expelled from Io [ http://antwrp.gsfc.…]. Amalthea is not massive enough for its internal gravity to make it spherical. Amalthea [ http://www.c3.lanl.…] was discovered in 1892 by Edward Barnard.
