Abstract: Asteroid 2024 PT5 was captured by Earth's gravitational field as a result of its approach and, while in geocentric orbit, became the so-called “satellite” of the Earth for two months. Observations of asteroid 2024 PT5 were conducted with the MTM-500M telescope of the Pulkovo Observatory as part of the program for studying near-Earth objects, which helped to refine the elements of the asteroid's orbit, study its orbital evolution, and assess the impact of non-gravitational effects and the period of axial rotation.

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