9223 Leifandersson
9223 Leifandersson, provisional designation , is a background asteroid from the inner regions of the asteroid belt, approximately 4.5 kilometers in diameter. It was discovered on 18 December 1995, by astronomers of the Spacewatch program at Kitt Peak National Observatory in Arizona, United States. The asteroid was named in memory of Swedish astronomer Leif Erland Andersson. The assumed stony asteroid has a rotation period of 3.758 hours. Orbit and classification Leifandersson is a non-family asteroid of the main belt's background population when applying the Hierarchical Clustering Method to its proper orbital elements. It has also been classified as a member of the Flora family (), a giant asteroid family and the largest family of stony asteroids in the main-belt. It orbits the Sun in the inner asteroid belt at a distance of 2.1–2.5 AU once every 3 years and 6 months (1,275 days; semi-major axis of 2.30 AU). Its orbit has an eccentricity of 0.07 and an inclination of 3° with respect to the ecliptic. The body's observation arc begins with its first observation as at Goethe Link Observatory in August 1948, or more than 47 years prior to its official discovery observation at Kitt Peak.
