10551

10551 is a stony asteroid located in the central region of the main asteroid belt. It was first observed on 4 March 1988 by the Lincoln Near-Earth Asteroid Research (LINEAR) project at the Lincoln Laboratory's Experimental Test Site in Socorro, New Mexico. The asteroid received its provisional designation 1988 EK15 before being numbered by the Minor Planet Center.

The orbit of 10551 has a semi-major axis of approximately 2.46 astronomical units, an eccentricity of 0.12, and an orbital period of 3.84 years. Its inclination relative to the ecliptic is about 6.1 degrees. Photometric observations suggest a rotation period of roughly 3.7 hours, indicating a relatively rapid spin for an object of its size. Spectroscopic analysis classifies it as an S-type asteroid, indicating a silicate-rich composition typical of the inner main belt.

As of the latest published data, the diameter of 10551 is estimated at about 8 kilometers, based on an assumed albedo of 0.20. The asteroid's absolute magnitude is 13.4. No official name has been assigned beyond its numerical designation, and it continues to be cataloged in routine surveys of main-belt bodies.
