Abstract: Within the framework of the Pulkovo program for studying near-Earth objects and the problem of asteroid and comet hazard, two near-Earth asteroids, 2023 DZ2 and 96590 (1998 XB), with axial rotation periods of 360 and 1.872$\cdot$10$^6$ s, respectively, were studied, which represents a very fast and extremely slow rotation. The orbital evolution of these objects, the circumstances of their close encounters, and the influence of non-gravitational effects were studied. Based on the obtained observational data, it was possible to determine the period of axial rotation of asteroid 2023 DZ2.

Keywords: near-earth asteroids, orbital evolution, non-gravitational effects.
