The time and minimum distances of approaches were calculated more than 100 open star clusters (OSCs) near the Solar System over the past 5 Myr. It was shown that the closest proximity of the centers of the OSCs to the Solar System usually exceeded 60

This paper presents an investigation of an old age open cluster King 11 using Gaia's Early Data Release 3 (EDR3) data. Considering the stars with membership probability ($P_{\mu}$) $> 90\%$, we identified 676 most probable cluster members within the

High-precision measurements of radial velocities of the M67 cluster members are used to calculate the radial-velocity dispersions in the stellar groups found earlier in the cluster’s corona. The previously detected feature in one of the groups (Gro
