319200

319200 is a numbered minor planet located in the outer region of the main asteroid belt. The asteroid was first observed on 25 October 2005 by the Catalina Sky Survey at the Mount Lemmon Observatory in Arizona. The provisional designation was 2005 UK75, and the Minor Planet Center assigned the permanent number 319200 after its orbit was well established.

The orbit of 319200 is moderately eccentric and inclined. Its semi‑major axis is approximately 2.78 astronomical units, placing it in the central main belt. The orbital period is about 4.4 years, while its eccentricity is 0.12 and its inclination relative to the ecliptic plane is 8.5 degrees. The asteroid’s perihelion distance is roughly 2.45 AU and its aphelion distance is 3.11 AU. It is not a member of any well‑defined dynamical family but is considered a typical background object in the Maria-belt region.

Physical characteristics derived from infrared surveys are sparse. Infrared data from the WISE mission indicate a diameter of roughly 7.5 km, with a low albedo in the range of 0.04 to 0.06, suggesting a carbonaceous composition. No rotational light‑curve has yet been published, so its rotation period, pole orientation, and shape remain unknown. Spectral classification has not been confirmed, but the low albedo is consistent with C‑type asteroids.

319200 has not yet been given a formal name. It remains commonly referred to by its numerical designation and provisional label. The asteroid continues to be monitored by surveys for future orbit refinement and potential physical characterization.
