23889

23889 is a minor planet in the asteroid belt, located between the orbits of Mars and Jupiter. It was discovered on October 13, 1998, by the Lincoln Near-Earth Asteroid Research (LINEAR) project at the Lincoln Laboratory's Experimental Test Site near Socorro, New Mexico. The asteroid is part of the main belt, which is the most populous region of the Solar System.

23889 has an estimated diameter of about 3.5 kilometers. Its orbit is relatively stable, with an orbital period of approximately 3.6 Earth years. The asteroid's semi-major axis is about 2.4 astronomical units (AU), and its eccentricity is low, indicating a nearly circular orbit. The inclination of its orbit to the ecliptic plane is around 1.5 degrees.

The spectral classification of 23889 is S-type, which suggests that it is composed primarily of silicate materials. This classification is based on its reflectance spectrum, which is characteristic of stony asteroids. The surface of 23889 is likely covered in a mixture of iron and magnesium silicates, similar to the composition of many other S-type asteroids.

The asteroid's rotation period is not well-determined, but it is believed to be relatively slow, on the order of several hours. This is typical for many asteroids in the main belt. The asteroid's albedo, or reflectivity, is estimated to be around 0.2, which is typical for S-type asteroids.

23889 is not considered a near-Earth object (NEO) because its orbit does not bring it close to Earth. However, its orbit does occasionally bring it close to the orbits of Mars and other asteroids in the main belt. The asteroid's orbit is well-studied, and its future trajectory is predictable for at least the next century.
