3212 Agricola, provisional designation 1938 DH2, is a stony Flora
Turku Observatory in Southwest Finland, on 19 February 1938, and named after reformer Mikael Agricola.[8]
Orbit and classification
The S-type asteroid is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun in the inner main-belt at a distance of 1.9–2.6 AU once every 3 years and 5 months (1,238 days). Its orbit has an eccentricity of 0.15 and an inclination of 8° with respect to the ecliptic.[1]
Physical characteristics
A rotational
albedo of 0.39,[5][6] while the Collaborative Asteroid Lightcurve Link assumes an intermediate albedo of 0.24 – derived from 8 Flora, the largest member and namesake of this orbital family – and calculates a larger diameter of 5.4 km (3.4 miles).[4]
