22146

22146 is a minor planet in the asteroid belt, located between the orbits of Mars and Jupiter. It was discovered on October 14, 1993, by astronomers Carolyn S. Shoemaker and David H. Levy at the Palomar Observatory in California, United States. The asteroid is part of the Flora family, a group of asteroids that share similar orbital elements and spectral characteristics, suggesting a common origin from a larger parent body that was disrupted by an impact.

The asteroid has an estimated diameter of approximately 5.6 kilometers and an orbital period of about 3.6 Earth years. Its orbit is moderately eccentric and inclined, with an average distance from the Sun of about 2.6 astronomical units. The Flora family, to which 22146 belongs, is one of the largest and most prominent families in the asteroid belt, containing over 1,000 known members.

The spectral classification of 22146 is S-type, indicating that it has a stony composition, likely consisting of silicate minerals. This classification is consistent with the overall composition of the Flora family asteroids. The asteroid's surface is relatively bright and has a low albedo, reflecting about 15% of the sunlight that hits it.

The study of 22146 and other members of the Flora family provides valuable insights into the early history of the solar system, including the processes of asteroid formation, collisional evolution, and the dynamics of the asteroid belt. Ongoing research and observations continue to refine our understanding of these fascinating celestial objects.
