Approach of the Orion’s Sword Complex (NGC 1977, NGC 1980, NGC 1981, M 42) and the Exoplanetary System TOI-2796

In this paper, we present the results of numerical calculations of the motion of the Orion’s Sword Complex (open star clusters NGC 1977, NGC 1980, NGC 1981, the Orion Nebula Cluster (ONC)—M 42) and the planetary system TOI-2796 with a single star around the galactic center. It is shown that Orion’s Sword objects approached TOI-2796 to a distance of up to ≈7 pc about two million years ago. An assessment of the possible change in the spatial velocity of a small body on the periphery of the Oort cloud TOI-2796 has been carried out. The result of the approach could have been the loss of the small body into interstellar space. The applicability of the apex method for searching for approaching objects has been estimated.
