1331524

1331524 is a numbered minor planet located in the intermediate region of the main asteroid belt. The object was first observed on 12 March 2004 by the Lincoln Near‑Earth Asteroid Research (LINEAR) survey at the Lincoln Laboratory’s Experimental Test Site in Socorro, New Mexico. After its initial discovery, the asteroid received its permanent designation following the confirmation of sufficient orbital observations, but it has not yet been given a formal name.

The asteroid’s orbit is moderately inclined, with a semimajor axis of 2.51 astronomical units, an eccentricity of 0.12, and an inclination of 5.8 degrees relative to the ecliptic. This results in an orbital period of roughly 3.96 years. The body is located near the Hygiea family but is not considered a confirmed family member. Its orbit is stable over the time scales measured, exhibiting no significant close approaches to the terrestrial planets.

Photometric observations have provided an absolute magnitude of 14.3. Assuming a typical dark carbonaceous albedo of 0.07, the estimated diameter is about 4.2 kilometres. The rotation period has not been established, and no spectral type has been firmly assigned to the object.

Because 1331524 has not been subject to a naming campaign, it carries no conventional name and is referenced exclusively by its numeric designation. The object is recorded in the Minor Planet Center database and is tracked by several observatories, contributing to the long‑term catalogue of main‑belt asteroids.
