113 Amalthea (/æməlˈθiːə/) is a stony Florian asteroid from the inner regions of the asteroid belt, approximately 50 kilometers (31 miles) in diameter. It was discovered on 12 March 1871, by German astronomer Robert Luther at the Bilk Observatory in Düsseldorf, Germany. The elongated S-type asteroid has a rotation period of 9.95 hours. It was named after Amalthea from Greek mythology. A purported satellite of Amalthea was announced in July 2017, but was later found to be a software error in July 2021.[2]
