985 Rosina, provisional designation 1922 MO, is a stony
Orbit and classification
Rosina is a
It orbits the Sun in the inner main-belt at a distance of 1.7–2.9 AU once every 3 years and 6 months (1,273 days). Its orbit has an eccentricity of 0.28 and an inclination of 4° with respect to the ecliptic.[1] The body's observation arc begins at Vienna Observatory, eight days after its official discovery observation at Heidelberg.[3]

Diameter and albedo
The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 8.18 kilometers based on an absolute magnitude of 12.8.[4]
Naming
This minor planet was named after a girl's name picked from the German popular calendar Der Lahrer hinkende Bote.(de)
Reinmuth's Calendar Girls
As with 913 Otila, 997 Priska and 1144 Oda, Reinmuth selected names from this calendar due to his many asteroid discoveries that he had trouble thinking of proper names. These names are not related to the discoverer's contemporaries. The author of the Dictionary of Minor Planet Names learned about Reinmuth's source of inspiration from private communications with Dutch astronomer Ingrid van Houten-Groeneveld, who worked as a young astronomer at Heidelberg.[2]
