25171

25171 is a minor planet in the outer region of the asteroid belt, orbiting the Sun at a distance of approximately 3.1 astronomical units. It was discovered on September 9, 1998, by the Lowell Observatory Near-Earth-Object Search (LONEOS) at Anderson Mesa Station. The asteroid has a diameter of about 10 kilometers and belongs to the Cybele group, a dynamical family of asteroids located beyond the main belt.

The orbital period of 25171 is roughly 5.6 Earth years, and its orbit has a moderate eccentricity of 0.11. The asteroid's semi-major axis is 3.12 AU, and its inclination to the ecliptic is 10.6 degrees. The spectral type of 25171 is C-type, indicating that it has a carbonaceous composition, which is common among asteroids in the outer belt.

The discovery of 25171 contributes to our understanding of the outer asteroid belt and the broader Solar System. It provides valuable data for studies on the formation and evolution of the Solar System, as well as the dynamics of minor planets in the outer regions. Further observations and analysis of 25171 will continue to enhance our knowledge of this intriguing celestial body.
