3212 Agricola, provisional designation 1938 DH2, is a stony asteroid from the inner regions of the asteroid belt, about 5 kilometers in diameter. It was discovered by Finnish astronomer Yrjö Väisälä at Turku Observatory in Southwest Finland, on 19 February 1938.[5]
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 at a distance of 1.9–2.6 AU once every 3 years and 5 months (1,238 days). Its orbit shows an eccentricity of 0.15 and is tilted by 8 degrees to the plane of the ecliptic.[1] In 2006, a photometric light-curve analysis rendered a rotation period of 9 hours with an amplitude in brightness of 0.07.[lower-alpha 1] Based on observations by the U.S. Wide-field Infrared Survey Explorer, the asteroid's surface has a high albedo of 0.39, while the Collaborative Asteroid Lightcurve Link assumes a more moderate value of 0.24, which is also identical to the albedo of the Flora family's namesake, the asteroid 8 Flora.[3][4]
The minor planet was named for Finnish clergyman Mikael Agricola (c. 1510–1557), bishop and reformer of Finland, often called "father of Finnish literature". Around 1538 he issued his ABC-kiria, the first book printed in the Finnish language, and in 1548 he translated the New Testament into Finnish.[2]
