The group is named after the asteroid (221) Eos . The family is believed to have emerged from a collision more than a billion years ago.
(39864) Poggiali was named on June 7, 2009 after the Italian aircraft navigator Maurizio Poggiali (1965–1997), who had a fatal accident on August 8, 1997 during a training flight .
