1171 Rusthawelia is a dark 70 km main-belt asteroid discovered on 3 October 1930 Sylvain Julien Victor Arend at Uccle.^[1] It was previously known as 525 Adelaide (A904 EB) discovered in 1904 by Max Wolf and observed only during the discovery opposition.^[1] 525 Adelaide was then assigned to 1908 EKa. A904 EB was confused with 31P/Schwassmann–Wachmann in 1929.^[3] Both the comet and the asteroid have the same orbital eccentricity of 0.19.
