42181

42181 is a minor planet in the asteroid belt, located between the orbits of Mars and Jupiter. It was discovered on October 24, 1998, by the Lincoln Near-Earth Asteroid Research (LINEAR) project. The asteroid is approximately 1.5 kilometers in diameter and has an orbital period of about 3.4 years. Its orbit is moderately inclined to the ecliptic plane, with an inclination of 10.5 degrees. The asteroid's semi-major axis is 2.28 astronomical units (AU), and its eccentricity is 0.21. The absolute magnitude of 42181 is 15.5, which indicates its brightness. The asteroid's spectral type is unknown, but it is likely a C-type asteroid, which are carbonaceous and often found in the outer regions of the asteroid belt. The discovery of 42181 contributes to our understanding of the asteroid belt and the formation of the solar system.
