22238

22238 is a minor planet in the outer region of the asteroid belt, approximately 10 kilometers in diameter. It was discovered on 11 October 1999, by astronomers of the Lincoln Near-Earth Asteroid Research team at the Lincoln Laboratory's Experimental Test Site near Socorro, New Mexico. 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 0.10 and an inclination of 11.7 degrees relative to the ecliptic. The absolute magnitude of 22238 is 13.5, indicating its size and albedo. The asteroid's spectral type is unknown, but it is likely a C-type asteroid, which are common in the outer asteroid belt and are characterized by their dark, carbonaceous surfaces. The rotation period of 22238 is approximately 5.5 hours. As of now, no moons have been discovered orbiting 22238. The asteroid's name is not yet assigned, and it is currently designated by its provisional designation, 1999 TQ243.
