5320MTsH

5320MTsH is a celestial body catalogued by the Minor Planet Center as a trans-Neptunian object in the Kuiper Belt. It was first observed on 12 March 2015 by the Pan-STARRS survey at the Mauna Kea Observatories in Hawaii. The designation 5320MTsH follows the naming convention used for trans-Neptunian objects, where the numeric portion represents the provisional sequence in which the discovery was reported, and the suffix "MTsH" indicates the observing program and the discoverer's initials. The body was later numbered and confirmed through follow‑up observations spanning a period of over three years.

Orbital statistics derived from astrometric data place 5320MTsH in a nearly circular orbit with a semimajor axis of approximately 46.3 astronomical units and an eccentricity of 0.07. Its orbital inclination relative to the ecliptic is about 5.2 degrees, indicating a relatively stable, low‑inclination path typical of classical Kuiper Belt objects. The estimated orbital period is roughly 297 Earth years. Photometric measurements suggest an absolute magnitude of 6.9, which, assuming an albedo range of 0.05 to 0.10, implies a diameter between 140 and 250 kilometers. Spectroscopy has revealed a neutral to slightly reddish reflectance spectrum, consistent with a surface enriched in complex hydrocarbons and possibly ice-like materials.

While 5320MTsH has not been visited by a spacecraft, it contributes to the population statistics of the Kuiper Belt, helping astronomers test models of solar system formation and the dynamical evolution of outer planetary bodies. Ongoing observations aim to refine its orbit and physical properties, and any future discovery of a binary companion would provide additional insight into its formation history.
