15951

15951 is a minor planet in the inner region of the asteroid belt between Mars and Jupiter. It was first observed on 21 July 1998 by the Lincoln Near‑Earth Asteroid Research (LINEAR) survey at the Lincoln Laboratory's Experimental Test Site in Socorro, New Mexico. The discovery was confirmed by follow‑up observations, and the object has been given the provisional designation 1998 TL. The Minor Planet Center officially numbered the asteroid 15951 in 2000, but it has not yet been named.

The orbit of 15951 takes it between 2.03 and 2.45 astronomical units from the Sun. Its semi‑major axis is 2.24 AU, with an eccentricity of 0.09 and an inclination of about 6.5 degrees relative to the ecliptic. The orbital period is roughly 3.55 years (1,297 days). The asteroid follows a nearly circular, gently tilted path typical of many inner‑belt bodies in the Flora family.

Photometric observations have suggested a diameter of approximately 4–5 kilometers, based on an assumed albedo of 0.24. Light‑curve analyses yield a rotation period near six hours, showing a relatively moderate spin rate. No significant spectral data or composition determinations have been published as of yet.

Because of its orbit and size, 15951 is considered a typical stony asteroid within the main belt. It does not pose any known threat to Earth and has not been targeted for any special scientific missions. Further observations could refine its physical parameters and improve dynamical models of inner‑belt asteroid populations.
