1424 Sundmania (prov. designation: 1937 AJ) is a large asteroid and rather slow rotator from the background population of the outer regions of the asteroid belt. It was discovered on 9 January 1937, by astronomer Yrjö Väisälä at the Turku Observatory in southwest Finland.[15] The dark X-type asteroid has a notably long rotation period of 93.7 hours and measures approximately 70 kilometers (43 miles) in diameter. It was named after Finnish astronomer and mathematician Karl F. Sundman.[2]
