 "Galileo" made its final satellite fly-by at a distance of approximately from Amalthea's center (at a height of about 160–170 km) on 5 November 2002, permitting the moon's mass to be accurately determined, while changing "Galileo's" trajectory so that it would plunge into Jupiter in September 2003 at the end of its mission.In 2006, Amalthea's orbit was refined with measurements from "New Horizons".Amalthea is the setting of several works of science fiction, including stories by Arthur C. Clarke, James Blish and Arkady and Boris Strugatsky.
