109472

109472 is an asteroid located in the outer region of the main asteroid belt between the orbits of Mars and Jupiter. It was discovered on October 24, 1992, by astronomers at the Spacewatch program at Kitt Peak National Observatory in Arizona, United States. The asteroid was given the provisional designation **1992 UO5** before being permanently numbered and named.

109472 is classified as a member of the outer main-belt asteroid population, with a semi-major axis of approximately 3.9 astronomical units (AU) from the Sun. Its orbit has an eccentricity of around 0.15, meaning it has a moderately elliptical path, and an inclination of roughly 1.5 degrees relative to the ecliptic plane. These orbital characteristics place it in the Cybele asteroid family, a group of asteroids with similar dynamical properties.

The asteroid has an estimated diameter of about 10 kilometers, based on observations of its brightness and assumed albedo. Little is known about its physical properties, such as shape, surface composition, or rotation period, though it is likely a dark, carbonaceous object typical of outer-belt asteroids. No significant close approaches to Earth have been recorded, and it is not classified as a potentially hazardous asteroid.

109472 has not been named by the International Astronomical Union (IAU), so it retains its numerical designation. It is occasionally observed by astronomers studying the distribution and characteristics of main-belt asteroids, particularly those in the outer regions. Its study contributes to understanding the composition and evolution of the early solar system.
