164359

164359 is a minor planet in the asteroid belt, located between the orbits of Mars and Jupiter. It was discovered on October 29, 1999, 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 2.7 astronomical units (AU). Its orbital period is about 4.5 Earth years, and it has an eccentricity of 0.14, indicating a relatively circular orbit.

The asteroid has a diameter of about 2.5 kilometers, based on its absolute magnitude of 16.1. Its rotation period is estimated to be around 5.5 hours. The surface composition of 164359 is not well-determined, but it is likely to be similar to other asteroids in the main belt, consisting primarily of rocky and metallic materials.

164359 does not have any known moons or companions. It is not considered a potentially hazardous asteroid, as its orbit does not bring it close to Earth's orbit. The asteroid's designation in the Minor Planet Center's database is 164359 (1999 UH11).
