131531

131531 is a minor planet located in the outer region of the asteroid belt, between the orbits of Mars and Jupiter. It was discovered on March 24, 2001, by the Lincoln Near-Earth Asteroid Research (LINEAR) team at the Lincoln Laboratory's Experimental Test Site near Socorro, New Mexico. The asteroid is classified as a main-belt asteroid, which means it orbits the Sun within the asteroid belt's main concentration.

The exact size of 131531 is not precisely known, but it is estimated to be between 2 and 5 kilometers in diameter. Its orbit has a semi-major axis of approximately 2.6 astronomical units (AU), with an eccentricity of about 0.15 and an inclination of roughly 12 degrees relative to the ecliptic plane. The asteroid completes one orbit around the Sun every 4.1 years.

131531 has not been named, and it is not known to have any significant physical characteristics or notable features. It is part of the background population of main-belt asteroids, which are numerous and relatively small compared to the larger asteroids like Ceres or Vesta.

The study of minor planets like 131531 contributes to our understanding of the formation and evolution of the solar system. By analyzing their orbits, sizes, and compositions, astronomers can piece together the history of the asteroid belt and the processes that shaped it.
