2148 Epeios /ɪˈpiːɒs/ is a mid-sized Jupiter trojan from the Greek camp, approximately 38 kilometers (24 miles) in diameter.
It was discovered on 24 October 1976, by Danish astronomer Richard Martin West at ESO's La Silla Observatory in northern Chile.
[1] The dark Jovian asteroid is the principal body of the proposed Epeios family and was named after Epeius from Greek mythology.
It is located in the leading Greek camp at the Gas Giant's L4 Lagrangian point, 60° ahead on its orbit (see Trojans in astronomy).
[1] Fernando Roig and Ricardo Gil-Hutton identified Epeios as the principal body of a small Jovian asteroid family, using the hierarchical clustering method (HCM), which looks for groupings of neighboring asteroids based on the smallest distances between them in the proper orbital element space.
