15460 Manca, provisional designation 1998 YD10, is a Koronian asteroid from the outer region of the asteroid belt, approximately 5 kilometers in diameter. It was discovered on 25 December 1998, by Italian astronomers Andrea Boattini and Luciano Tesi at Pistoia Mountains Astronomical Observatory in San Marcello Pistoiese, central Italy.
The stony S-type asteroid belongs to the Koronis family, a group consisting of few hundred known bodies with nearly ecliptical orbits. It is also classified as a X-type asteroid by Pan-STARRS' large-scale survey.Manca orbits the Sun at a distance of 2.6–3.2 AU once every 4 years and 11 months (1,809 days). Its orbit has an eccentricity of 0.09 and an inclination of 3° with respect to the ecliptic. The first precovery was taken at Palomar Observatory in 1950, extending the asteroid's observation arc by 48 years prior to its discovery.
In August 2012, a rotational light-curve was obtained for Manca from photometric observations made at the Palomar Transient Factory, California. It gave it a rotation period of 7.2723±0.0209 hours with a brightness variation of 0.22 magnitude (U=2).
