13981

13981 is a minor planet in the outer region of the asteroid belt, orbiting the Sun between Mars and Jupiter. It was discovered on September 24, 1960, by the Indiana Asteroid Program at Goethe Link Observatory in Brooklyn, Indiana. The asteroid is classified as a non-family asteroid, meaning it does not belong to any known asteroid family. Its orbit is relatively stable, with an eccentricity of 0.106 and an inclination of 10.06 degrees relative to the ecliptic. The asteroid has an absolute magnitude of 12.9, which corresponds to a diameter of approximately 8.5 kilometers, assuming an albedo of 0.20. The rotational period of 13981 is not well-determined, but it is estimated to be around 12 hours. The asteroid's spectral type is not definitively known, but it is likely to be of the C-type, which is characteristic of carbonaceous chondrites. 13981 has not been visited by any spacecraft, and its surface composition and other properties remain largely unknown.
