22163

22163 is a minor planet in the asteroid belt, located between the orbits of Mars and Jupiter. It was discovered on October 24, 1993, by astronomers Carolyn S. Shoemaker and David H. Levy at the Palomar Observatory in California, United States. The asteroid is named after the year of its discovery, 22163.

The asteroid has an estimated diameter of about 4 kilometers and orbits the Sun with a semi-major axis of approximately 2.7 astronomical units (AU). Its orbital period is roughly 4.5 Earth years. The orbital eccentricity of 22163 is 0.12, indicating a relatively circular orbit.

The spectral classification of 22163 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.

22163 does not have any known moons or companions. Its rotation period is approximately 5.5 hours, and its axial tilt is estimated to be around 30 degrees.

The asteroid's orbit does not bring it close to Earth, and it is not considered a potentially hazardous object. As of now, there are no plans for missions to study 22163 in detail. However, its discovery and ongoing observations contribute to our understanding of the asteroid belt and the solar system's formation and evolution.
