113 Amalthea is a fairly typical rocky main-belt asteroid orbiting in the inner regions of the belt. It was discovered by R. Luther on March 12 1871. The name comes from Amalthea of Greek mythology. One of Jupiter’s inner small satellites unrelated to 113 Amalthea is also called Amalthea.Amalthea is thought to be a fragment from the mantle of a Vesta-sized 300–600 km diameter parent body that broke up around one billion years ago with the other major remnant being 9 Metis.
