Rotation period as a function of diameter for the objects in this work. The left panel shows the full distribution, with asteroids from the Lightcurve Database (LCDB) and SsODNet with U ≥ 2 in grey and near-Earth asteroids (NEAs) in orange. The 161 new NEAs with rotation periods derived in this paper are plotted in dark blue. Diameters were estimated from absolute magnitudes assuming a geometric albedo p_V = 0.15. Cohesive spin limits for weak rubble-pile material (C ~ 10 Pa), lunar-like regolith (C ~ 1 kPa), and a size-dependent monolithic strength (C ∝ D^−0.5) are overplotted for reference. The right panel provides a zoomed-in image of the sub-140 m size range, where our survey is primarily focused.
