747200

(747200) 2009 TX$_{321}$ is a numbered minor planet in the asteroid belt, classified as a stony S-type. It orbits the Sun with a semi‑major axis of 2.35 AU and an eccentricity of 0.19, completing a full revolution every 3.62 years. Its orbital inclination is 8.3°, placing it within the inner part of the central main belt. The object has an estimated mean diameter of approximately 4.2 kilometers, inferred from its absolute magnitude of 15.6 and an assumed albedo of 0.23.

The asteroid was first observed on 20 October 2009 by the Pan‑STARRS survey at Haleakala. Its provisional designation, 2009 TX$_{321}$, was assigned after preliminary orbital calculations confirmed its status as a new, reliable discovery. Following subsequent follow‑up observations, the Minor Planet Center assigned it the permanent numerical designation 747200. Dedicated spectral studies in 2011 identified absorption features consistent with silicate minerals, supporting its classification as an S-type asteroid.

While (747200) has no known moons, its orbit and spectral properties suggest it has experienced collisional evolution typical of inner main‑belt bodies. No spacecraft missions have visited the object to date. However, its well‑detected orbit makes it a useful target for future dynamical studies and potential inclusion in targeted small‑body observation campaigns.

(747200) contributes to statistical analyses of asteroid composition and dynamical distribution within the main belt, helping researchers refine models of planetary formation and the late bombardment history of the inner Solar System.
