10208 Germanicus, provisional designation 1997 QN1, is a stony binary[10] asteroid from the inner regions of the asteroid belt, approximately 4 kilometers in diameter. It was discovered on 30 August 1997, at the Santa Lucia Stroncone Astronomical Observatory in Stroncone, Italy, and named for Germanicus, an ancient Roman general and nephew of Tiberius.[2] A moon orbits the asteroid with an orbital period of 2 days, 10 hours, and 48 minutes.[10]
Germanicus orbits the Sun at a distance of 1.8–2.7 AU once every 3 years and 4 months (1,221 days). Its orbit has an eccentricity of 0.20 and an inclination of 5° with respect to the ecliptic.[1]
