131507

131507 is a minor planet in the outer region of the asteroid belt, orbiting the Sun between Mars and Jupiter. It was discovered on September 11, 2001, by astronomers at the Lincoln Near-Earth Asteroid Research (LINEAR) project. The asteroid is classified as a main-belt asteroid, with a semi-major axis of approximately 3.1 astronomical units (AU). Its orbital period is about 5.5 Earth years, and it has an eccentricity of 0.15, indicating a relatively circular orbit.

The size of 131507 is estimated to be around 3.5 kilometers in diameter, based on its absolute magnitude of 15.5. Its spectral type is classified as X, which suggests a primitive composition, possibly including carbonaceous materials. This classification is typical for many asteroids in the outer asteroid belt.

131507 has not been observed to have any known moons or companions. Its rotation period is not well-determined, but it is estimated to be around 5.5 hours. The asteroid's surface is likely covered in regolith, a layer of loose material resulting from micrometeoroid impacts.

The discovery and study of 131507 contribute to our understanding of the asteroid belt's composition and dynamics. It is one of many objects that help scientists piece together the history and evolution of the solar system.
