9115 Battisti, provisional designation 1997 DG, is a stony Vestian asteroid from the inner regions of the asteroid belt, about 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.[5]
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 shows an eccentricity of 0.09 and an inclination of 5 degrees from the plane of the ecliptic.[1]
In 2010, a photometric light-curve analysis at the U.S. Palomar Transient Factory in California 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.[4] The Collaborative Asteroid Lightcurve Link assumes a standard albedo of 0.20 for stony asteroids and calculates the body's diameter to measure about of 5.1 kilometers.[3]
The asteroid is named in memory of Lucio Battisti (1943–1998), the innovative Italian singer-songwriter considered to be one of the best-known and most influential musicians and authors in Italian pop/rock music history.[6] He wrote many songs for himself and other singers, among them Emozioni and I giardini di marzo. Beginning in 1973, he lived in a small village in the neighborhood of the observatory at Sormano, where this minor planet was discovered.[2]
