NotesAutomedon is a Trojan asteroid of Jupiter, preceding that giant planet along its orbit by sixty degrees (and with significant orbital inclination). This is a body belonging to the dark D-type asteroid classification, an otherwise relatively rare type that is found most commonly among Trojans like Automedon.

An asteroid some 89 km in diameter that pursues a twelve-year orbit around the Sun far beyond the farthest edge of the main Asteroid Belt. In fact, its orbit is similar to that of Jupiter, but inclined by 21° to the plane of the Ecliptic.
