Abstract
The astrometric and photometric series of observations of potentially hazardous asteroid (276033) 2002 AJ129 were obtained with MTM-500M telescope of Pulkovo Observatory in the period of its close approach to the Earth on February 4, 2018. The orbital evolution was studied and the influence of non-gravitational effects (solar radiation pressure and the Yarkovsky effect) was estimated. The axial rotation period (P = 3.9222 ± 0.0008 h) of the asteroid and the color indices (B–V = 0.687 ± 0.050, V–R = 0.405 ± 0.027, R–I = 0.178 ± 0.044) were determined from the photometric series of observations.
