Note 9 — Chapter V · THE ASTEROIDS, A FAMILY OF DWARF WORLDS
Reading edition
"Since the discovery of Eros, the extraordinary position of its orbit has led to the suggestion that possibly Mars itself, instead of being regarded as primarily a major planet, belonging to the terrestrial group, ought rather to be considered as the greatest of the asteroids, and a part of the original body from which the asteroidal system was formed."—J. Bauschinger, Astronomische Nachrichten, No. 3542.
