    525 Adelaide is an S-type asteroid belonging to the Flora family in the Main Belt.

    The object A904 EB discovered March 14, 1904 by Max Wolf was named 525 Adelaide and was subsequently lost. Later, the object 1930 TA discovered October 3, 1930 by Sylvain Arend was named 1171 Rusthawelia. In those pre-computer days, it was not realized until 1958 that these were one and the same object. The name Rusthawelia was kept (and discovery credited to Arend); the name 525 Adelaide was reused for the object 1908 EKa discovered October 21, 1908 by Joel Hastings Metcalf.
