It was discovered 9 May 1905 by German astronomer Paul Götz at Heidelberg, and was named for a female character in the novel Thus Spoke Zarathustra by Friedrich Nietzsche. Based on observations made with the IRAS, 564 Dudu has a diameter of 49.57 ± 4.9 km, a geometric albedo of 0.0484 ± 0.011, and an absolute magnitude (H-value) of 10.43.[3] References1. ^{{Cite web |url=http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=564;cad=1 |title=564 Dudu (1905 QM) |work=JPL Small-Body Database |publisher=NASA/Jet Propulsion Laboratory |access-date=5 May 2016}} [2]2. ^1 {{citation | last1=Tedesco | first1=Edward F. | last2=Noah | first2=Paul V. | last3=Noah | first3=Meg | last4=Price | first4=Stephan D. | title=The Supplemental IRAS Minor Planet Survey | journal=The Astronomical Journal | date=February 2002 | volume=123 | issue=2 | pages=1056–1085 | bibcode=2002AJ....123.1056T | doi=10.1086/338320}} }} External links
