    9115 Battisti, provisional designation 1997 DG, is a stony Vestian asteroid from the inner regions of the asteroid belt, approximately 5.5 kilometers in diameter. It was discovered by Italian astronomers Piero Sicoli and Francesco Manca at Sormano Astronomical Observatory in northern Italy, on 27 February 1997.[7]

    The stony S-type asteroid is a member of the Vestian family. It orbits the Sun at a distance of 2.2–2.6 AU once every 3 years and 9 months (1,354 days). Its orbit has an eccentricity of 0.09 and an inclination of 5° with respect to the ecliptic.[1] The first used observation was made at Palomar Observatory in 1980, extending the asteroid's observation arc by 17 years prior to its discovery.[7]

    In November 2010, a rotational light-curve for this asteroid obtained from photometric observations at the U.S. Palomar Transient Factory in California. It rendered a rotation period of 5.0228±0.0025 hours with a brightness amplitude of 0.07 in magnitude (U=1), typically indicating that the asteroid has a nearly spheroidal shape.[5]

    According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the asteroid measures 5.7 kilometers in diameter and its surface has an albedo of 0.195,[4] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo of 0.20 for stony asteroids and calculates a diameter of 5.1 kilometers, based on an absolute magnitude of 13.82.[3]

    The minor planet is named in memory of Italian singer-songwriter Lucio Battisti (1943–1998).[8] In the 1970s, Battisti lived in a small village near Sormano, location of the discovering observatory.[2] Naming citation was published on 8 December 1998, three months after his death (M.P.C. 33389).[9]
