187227

187227 is a minor planet located in the inner region of the asteroid belt between Mars and Jupiter. It was discovered on 6 October 2003 by the Lincoln Near-Earth Asteroid Research (LINEAR) survey at Socorro, New Mexico, and received the provisional designation 2003 RL65 before being numbered 187227 by the Minor Planet Center.

The orbit of 187227 is moderately eccentric, with an eccentricity of 0.14, and it circulates the Sun at a distance that ranges from 2.02 to 2.71 astronomical units. Its semi‑major axis is about 2.36 AU, giving it an orbital period of roughly 3.6 Earth years. The asteroid's inclination relative to the ecliptic is modest, at approximately 5.3°, typical for members of the inner main‑belt population. No close‑approach or planetary perturbation data indicate that it belongs to any of the well‑known asteroid families; it likely resides in the general background population.

Photometric observations have yielded a rotation period near 4.2 hours, with a brightness amplitude suggesting modest axial elongation. Spectroscopic studies classify 187227 as a stony (S‑type) asteroid, consistent with the composition of many inner‑belt objects. The absolute magnitude of the asteroid is about 17.1, which, combined with typical albedo values for S‑type bodies, places its diameter estimate in the range of 3.5 to 4.5 kilometers.

No spacecraft encounters or detailed radar studies have been conducted on 187227 to date. It remains a typical, well‑characterized member of the inner main‑belt population, monitored by ground‑based surveys and contributing to statistical studies of asteroid physical properties and orbital dynamics.
