3181 Ahnert, provisional designation 1964 EC, is a stony Flora asteroid from the inner regions of the asteroid belt, about 8 kilometers in diameter. It was discovered by German astronomer Freimut Börngen at the Karl Schwarzschild Observatory in Tautenburg, eastern Germany, on 8 March 1964.[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 2.1–2.4 AU once every 3 years and 4 months (1,216 days). Its orbit has an eccentricity of 0.07 and an inclination of 4° with respect to the ecliptic.[1] The first precovery was obtained at Lowell Observatory in 1931, extending the asteroid's observation arc by 33 years prior to its discovery.[8]
