525 Adelaide is anS-type asteroid[1] belonging to theFlora family in theMain Belt. It was discovered 21 October 1908 byJoel Hastings Metcalf.
Previously, the object A904 EB, discovered 14 March 1904 byMax Wolf, had been named 525 Adelaide but was subsequently lost. When it was rediscovered 3 October 1930 bySylvain Arend as1930 TA, it was named1171 Rusthawelia. Some 28 years passed before the two objects were realized to be the same. 1930 TA retained the name Rusthawelia (and discovery credited to Arend); the name 525 Adelaide was reused for the object 1908 EKa.
Another confusion occurred in 1929, one year before Arend's discovery, when American astronomerAnne Sewell Young thought to have found long-lost "Adelaide", when in fact she mistook the asteroid for comet31P/Schwassmann–Wachmann that had a very similarorbital eccentricity.[2]
