333 Badenia (/bəˈdiːniə/ bə-DEE-nee-ə; prov. designation: A892 QA or 1892 A) is a large background asteroid, approximately 72 kilometers (45 miles) in diameter, located the outer region of the asteroid belt. It was discovered on 22 August 1892, by astronomer Max Wolf at the Heidelberg-Königstuhl State Observatory in southwest Germany.[1] The carbonaceous C-type asteroid has a rotation period of 9.9 hours. It was named after the historical Grand Duchy of Baden that existed until 1918, and where the discovering observatory is located.[2] Badenia was the first asteroid to receive a provisional designation.
