The Vatican Observatory announced that an asteroid has been named in honor of Pope Leo XIII, who formally reestablished the observatory in 1891. The remaining three asteroids have been named for other key figures in the history of the Vatican Observatory, which traces its roots to the solar calendar reform of Pope Gregory XIII in 1582.
