722 Frieda (prov. designation:A911 UNor1911 NA) is a bright background asteroid and slow rotator from the inner regions of the asteroid belt. It was discovered by Austrian astronomer Johann Palisa at the Vienna Observatory on 18 October 1911.[1] The stony S-type asteroid has a notably long rotation period of 131.1 hours and measures approximately 9 kilometers (6 miles) in diameter. It was named after Frieda Hillebrand, daughter of Austrian astronomer Karl Hillebrand [de] (1861–1939), and grand-daughter of Edmund Weiss (1837–1917) who had been the director of the discovering observatory.[3]
