is a sub-kilometer asteroid, classified as near-Earth object of the Amor group orbiting between Earth and Mars. It was first observed by the Lincoln Near-Earth Asteroid Research (LINEAR) at the Lincoln Laboratory ETS on 20 September 2003. As of 2026, this minor planet has not been named.
is an Amor asteroid – a subgroup of near-Earth asteroids that approach the orbit of Earth from beyond, but do not cross it. It orbits the Sun at a distance of 1.0–1.2 AU once every 14 months (436 days; semi-major axis of 1.22 AU). Its orbit has an eccentricity of 0.08 and an inclination of 3° with respect to the ecliptic. The body's observation arc begins with its first observation by LINEAR in 2003.
The object's spectral type remains unknown. Using a magnitude-to-diameter conversion, measures 75 and 140 meters in diameter, based on an absolute magnitude of 23.0 and an assumed albedo of 0.20 (S-type) and 0.057 (C-type), respectively. was being considered by the European Space Agency as a candidate target for the Don Quijote mission to study the effects of impacting a spacecraft into an asteroid.
