    12848 Agostino, provisional designation 1997 NK10, is a stony Eunomia asteroid from the middle region of the asteroid belt, approximately 5 kilometers in diameter. It was discovered on 10 July 1997, by Italian astronomer Andrea Boattini at the Campo Imperatore Observatory in the Gran Sasso massif of central Italy.[7]

    The asteroid is a member of the Eunomia family, a large group of stony S-type asteroids and the most prominent family in the intermediate main-belt. It orbits the Sun at a distance of 2.4–2.8 AU once every 4 years and 2 months (1,534 days). Its orbit has an eccentricity of 0.09 and an inclination of 15° with respect to the ecliptic.[1] The first precovery was obtained at Palomar Observatory in 1950, extending the asteroid's observation arc by 47 years prior to its discovery.[7]

    Two rotational light-curves of this asteroid were obtained from photometric observations made at the U.S. Palomar Transient Factory in August 2010 and February 2012, respectively. The light-curves gave a rotation period of 6.3350±0.0258 and 6.3225±0.0052 hours with a respective brightness variation of 0.51 and 0.84 in magnitude (U=2/2).[5] According to the NEOWISE mission of NASA's space-based Wide-field Infrared Survey Explorer, the asteroid measures 4.9 kilometers in diameter and its surface has an albedo of 0.23,[4] while the Collaborative Asteroid Lightcurve Link assumes an albedo of 0.21 – derived from 15 Eunomia, the family's largest member and namesake – and calculates a diameter of 4.6 kilometers.[3]

    The minor planet was named after Agostino Boattini (b. 1932), the father of the discoverer.[2] Naming citation was published on 9 May 2001 (M.P.C. 42673).[8]
