1171 Rusthawelia, provisional designation 1930 TA, is a large and dark background asteroid, approximately 72 kilometers (45 miles) in diameter, located in the outer regions of the asteroid belt. It was discovered on 3 October 1930, by Belgian astronomer Sylvain Arend at the Royal Observatory of Belgium in Uccle, and was an unnoticed rediscovery of a lost minor planet then known as "Adelaide".[1] As the asteroid was already named for Georgian poet Shota Rustaveli when the rediscovery was realized, its former designation was given to another asteroid instead, which is now known as 525 Adelaide.[2] Rusthawelia is a primitive P-type asteroid and has a rotation period of 11 hours.
