It was discovered on 24 September 2001, by astronomers at the Lincoln Laboratory ETS (Lincoln Near-Earth Asteroid Research or LINEAR) project. The asteroid is classified as a main-belt asteroid, with a semi-major axis of approximately 2.67 astronomical units (AU). Its orbital period is about 4.28 years, and its eccentricity is 0.164. The asteroid has an absolute magnitude of 16.0, which corresponds to a diameter of roughly 2 kilometers, assuming an albedo of 0.15. The rotational period of 111373 is not yet determined. The asteroid's spectral type is not yet classified, but it is expected to be of the S-type, which is common among main-belt asteroids. The asteroid's name is not yet assigned, and it is currently known by its provisional designation, 2001 SG273.
