The problem of the kinematics of the approach of open star clusters and stars with exoplanets is considered. It was found that the cluster NGC 1977, located in the region of Orion’s Sword, in past epochs approached in space the star TOI-2796, which has a planetary system. The parameters of the approach—time and distance between the objects—were obtained. For this, numerical calculations of the orbit around the Galactic Center were carried out. It is shown that these objects approached at a distance of 7. 8 pc about 4. 4 million years ago. This approach could have had a gravitational effect on the Oort cloud analogue TOI-2796, leading to a change in the orbital elements of small bodies located in its outer parts. It is important to note that the observed effect could be the loss of objects from the TOI-2796 planetary system into interstellar space. This work continues our research 1 using SIMBAD data.
