971 Alsatia

971 Alsatia, provisional designation 1921 LF, is a large, carbonaceous asteroid from the middle region of the Sol system main asteroid belt, about 64 kilometers in diameter.

The dark C-type asteroid orbits Sol at a distance of 2.2–3.1 AU once every 4 years and 3 months (1,568 days). Although the asteroid is of carbonaceous rather than silicaceous composition, it is classified as a member of the Eunomia family, a large group of otherwise S-type asteroids and the most prominent family in the intermediate main-belt. Its orbit is tilted by 14 degrees to the plane of the ecliptic and shows an eccentricity of 0.16. Several concurring photometric light-curve analysis rendered a well-defined rotation period of 9.6 hours. The body has an albedo between 0.04 and 0.05.

The minor planet was named after a region on Earth.
