20147

20147 is a minor planet in the asteroid belt, located between the orbits of Mars and Jupiter. It was discovered on 14 October 1999 by the Lincoln Near-Earth Asteroid Research (LINEAR) team at the Lincoln Laboratory's Experimental Test Site near Socorro, New Mexico. The asteroid is approximately 3.5 kilometers in diameter and has an orbital period of about 4.1 years. Its orbit is moderately inclined to the ecliptic plane, with an inclination of 10.5 degrees. The asteroid's rotation period is approximately 5.7 hours. 20147 is classified as a main-belt asteroid, specifically a member of the Flora family, which is a large group of asteroids sharing similar orbital characteristics. The Flora family is believed to have originated from a single parent body that was disrupted by a collision. The asteroid's spectral type is S, indicating that it has a stony composition. 20147 has not been observed to have any moons or companions. The asteroid's absolute magnitude is 13.6, which is a measure of its brightness. The asteroid's name is derived from its provisional designation, which is a temporary name given to newly discovered asteroids. The asteroid's official name has not yet been assigned.
