18431895
18431895 is a notable astronomical object identified by its minor planet number. It was discovered on October 10, 2005, by the Spacewatch project at the Kitt Peak National Observatory in Arizona, USA. The object is classified as a trans-Neptunian object (TNO), specifically a plutino, which means it has a 2:3 orbital resonance with Neptune. This resonance causes its orbit to be influenced by Neptune's gravity, leading to a stable, elongated orbit that keeps it in a specific relationship with Neptune.
18431895 has an estimated diameter of approximately 240 kilometers, making it one of the larger known TNOs.
The discovery and study of 18431895 contribute to our understanding of the outer Solar System and the
