Collisional history of the EL original planetesimal. The EL planetesimal accreted in the terrestrial planet region where it suffered a collisional event. A fragment of it –the Athor family progenitor– was transported to the current location of Athor in the inner main belt by a dynamical process. About 900 Myr later, the Athor family progenitor suffered an additional collisional event that led to the formation of the present Athor family. Meteorites are now transported from the Athor family to Earth via well-established routes.
