1496 Turku
1496 Turku, provisional designation , is a Florian asteroid from the inner regions of the asteroid belt, approximately 8 kilometers in diameter. It was discovered on 22 September 1938, by astronomer Yrjö Väisälä at the Iso-Heikkilä Observatory in Turku, Finland. The asteroid was named for the Finnish city of Turku. Orbit and classification Turku is a member of the Flora family (), a giant asteroid family and the largest family of stony asteroids in the main belt. It is, however, a non-family asteroid from the main belt's background population when applying the Hierarchical Clustering Method to its proper orbital elements. It orbits the Sun in the inner main-belt at a distance of 1.8–2.6 AU once every 3 years and 3 months (1,197 days). Its orbit has an eccentricity of 0.16 and an inclination of 3° with respect to the ecliptic. The body's observation arc begins with its first identification as at Johannesburg Observatory in August 1928, more than 10 years prior to its official discovery observation at Turku. Physical characteristics Turku is an assumed S-type asteroid, which is also the Flora family's overall spectral type. Rotation period and poles In April 2006, a rotational lightcurve of Turku was obtained from
