173320
173320 is a minor planet in the outer region of the asteroid belt, approximately 10 kilometers in diameter. It was discovered on 14 September 2001, by astronomers of the Lincoln Near-Earth Asteroid Research team at the Lincoln Laboratory's Experimental Test Site near Socorro, New Mexico. The object is classified as a non-family asteroid of the main belt, with a semi-major axis of 3.16 AU. Its orbit has an eccentricity of 0.13 and an inclination of 16 degrees with respect to the ecliptic. The rotational period of 173320 is approximately 3.8 hours. The asteroid's spectral type is unknown, but it is likely a C-type asteroid, which are carbonaceous and typically found in the outer asteroid belt. The discovery of 173320 contributes to our understanding of the composition and dynamics of the asteroid belt.
