Orbit
Nanna is a dark C-type asteroid. It orbits the Sun at a distance of 2.2–3.6 AU once every 4 years and 11 months (1,797 days). Its orbit has an eccentricity of 0.25 and an inclination of 6° with respect to the ecliptic.[1] In 1926, it was first identified as 1926 RH, extending the body's observation arc by 5 years prior to its official discovery observation.[13]
