Dudu, asteroid 564 (the 564th asteroid to be discovered, on May 9, 1905), is approximately 50 kilometers in diameter and has an orbital period of 4.6 years. It was named after a character in Nietzsche’s Thus Spake Zarathustra. The unusual name of this planetoid (the connotations of which are obvious enough) led to its inclusion in The Asteroid Ephemeris: Dudu, Dembowska, Pittsburgh, Frigga, Batya Stark and Mark Pottenger’s tour de force of astrological humor.
