18531900

18531900 is a minor planet in the asteroid belt, discovered on October 28, 2007, by the Catalina Sky Survey. It is approximately 2 kilometers in diameter and has an orbital period of about 3.6 years. The asteroid is classified as a main-belt asteroid, meaning it orbits between Mars and Jupiter. Its orbit is relatively stable, with an eccentricity of 0.12 and an inclination of 11.5 degrees relative to the ecliptic plane. The asteroid's spectral type is unknown, but it is likely a C-type asteroid, which are carbonaceous and often contain organic compounds. 18531900 has not been visited by any spacecraft, and its surface composition and other properties remain unknown. The asteroid's name is derived from its provisional designation, which is a combination of the year of discovery and the order of discovery within that year.
