54548

54548 is a numbered minor planet located in the inner region of the asteroid main belt. The object was first observed on 19 May 2001 by the Lincoln Near-Earth Asteroid Research (LINEAR) survey at the Lincoln Laboratory’s Experimental Test Site near Socorro, New Mexico. Its provisional designation was 2001 SV22, and it received the permanent number 54548 in 2005 after its orbit was well determined from multiple oppositions. The asteroid has not yet been assigned a proper name and remains referred to as 54548 in scientific literature.

Orbital analysis indicates a semi‑major axis of approximately 2.44 astronomical units, an eccentricity of about 0.17, and an inclination of 11 degrees relative to the ecliptic. Its orbital period is roughly 3.79 years (1,384 days). The body follows a typical S‑type orbit in the inner main belt and is part of the background population rather than a recognized dynamical family.

Photometric observations suggest a rotation period of about 4.5 hours with a light‑curve amplitude implying a somewhat elongated shape. The absolute magnitude of 14.7 points to a diameter of roughly 4–5 kilometers, assuming an albedo typical of S‑type asteroids. Spectroscopic data are limited, but available measurements are consistent with a silicate‑rich composition.

Given its size and orbit, 54548 is considered an ordinary main‑belt asteroid. It has not been targeted for spacecraft encounters, but it contributes to studies of asteroid belt dynamics and the characterization of S‑type bodies in the inner Solar System.
