53186

53186 is a minor planet in the asteroid belt, orbiting the Sun between Mars and Jupiter. It was discovered on September 24, 1999, by the Lincoln Near-Earth Asteroid Research (LINEAR) project, a collaborative effort between the United States Air Force, NASA, and MIT Lincoln Laboratory. The asteroid is approximately 1.5 kilometers in diameter and has an orbital period of about 3.5 years. Its orbit is relatively stable, with a semi-major axis of approximately 2.6 astronomical units (AU) and an eccentricity of around 0.1. The asteroid's spectral type is classified as S-type, indicating a stony composition. 53186 is not considered a near-Earth object, as its orbit does not bring it close to Earth. It is named after the discoverer, the Lincoln Laboratory, in recognition of their contributions to asteroid research and tracking.
