92 Undina (IPAEng|ʌnˈdaɪnə "un-dye'-nə," or as Latin "Undīna") is a large main belt asteroid. It has an unusually high albedo and an M-type spectrum. It was discovered by C. H. F. Peters on July 7, 1867. It is named the eponymous heroine of Undine, a popular novella by Friedrich de la Motte Fouqué. Undina is a member of the Veritas asteroid family, which formed some eight million years ago. See 490 Veritas for details.
