158205

158205 is a main‑belt asteroid that was first observed on 6 September 2000 by the Lincoln Near–Earth Asteroid Research (LINEAR) program at the Oschin Schmidt telescope in Socorro, New Mexico. It is numbered upon the confirmation of its orbit, following the standard procedures of the Minor Planet Center. The asteroid follows an orbit located in the central portion of the main belt, with a semi‑major axis of approximately 2.45 AU. Its orbital eccentricity is modest, around 0.10, and it maintains an inclination of roughly 3.5° relative to the ecliptic. These parameters give it an orbital period of about 4.1 years.

Photometric observations suggest that 158205 has a low albedo characteristic of C‑type (carbonaceous) asteroids, implying a composition rich in carbonaceous material and possibly hydrated minerals. Estimates of its size based on its absolute magnitude (H ≈ 14.1) and an assumed albedo of 0.06 yield a diameter near 8 km, although radar and thermal infrared measurements have not yet provided a more precise dimension. Spectroscopic studies are limited, but the object likely shares the primitive, unaltered material typical of the inner belt.

The asteroid has not been given a formal name yet; it remains identified solely by its provisional designation until a naming citation is proposed and approved by the International Astronomical Union. As of the latest data available, it is occasionally observed in opposition and contributes to the statistical understanding of the population distribution and dynamics within the central main belt.
