21163 is a minor planet in the asteroid belt, located between the orbits of Mars and Jupiter. It was discovered on September 24, 1960, by the Indiana Asteroid Program at Goethe Link Observatory in Indiana, United States. The asteroid is named after the year of its discovery, 1960. It has an estimated diameter of approximately 10 kilometers and orbits the Sun with a period of about 4.6 years. The orbital eccentricity of 21163 is 0.14, indicating a relatively circular orbit. The asteroid's absolute magnitude is 12.5, which is a measure of its brightness. 21163 is classified as a main-belt asteroid, a group of asteroids that orbit the Sun primarily between Mars and Jupiter. The asteroid's spectral type is unknown, but it is likely to be a C-type asteroid, which are carbonaceous and typically found in the outer regions of the asteroid belt. 21163 is not a potentially hazardous asteroid, as its orbit does not bring it close to Earth.
