    1155 Aënna, provisional designation 1928 BD, is a main belt asteroid, approximately 12 kilometers in diameter. The X-type asteroid revolves around the Sun once every 3.87 years. It was discovered by Karl Reinmuth at Heidelberg Observatory, Germany on January 26, 1928.[1]

    It was named after one of the first international journals in the field of astronomy, Astronomische Nachrichten. The construct "Aënna" contains the German pronunciation of the initials "A" and "N" followed by the feminine ending. The name was proposed by the Astronomisches Rechen-Institut.[2]
