Halaesus was a son of Agamemnon {see planet (911)}. This minor planet is dynamically paired with (2759) Idomeneus, and like the Greek warrior Idomeneus, Halaesus found a home in Italy, settling on Mount Massiscus in Campania. Unlike Idomeneus, Halaesus missed joining the Trojan War and the sack of Troy. He made up for this later, for he fought against Aeneas {see planet (1172)} in the war for Italy, where he killed a large number of Trojans on Italian soil. (M 22248)
