Study of the linear dimensions of very young open star clusters (age less than 15 my) shows that in the observable part of the Galaxy the diameter of clusters increases on the average with distance from the galactic center, the variation being especially pronounced around a distance from the galactic center of 11 kpc. Both the direction and the size of the observed increase may be interpreted in terms of the change of the Jeans critical radius throughout the Galaxy. The required increase of the Jeans radius with distance from the galactic center may be accounted for by the decrease in the mean gas density throughout the Galaxy and by the decrease in the compression effects of the galactic shock waves or whatever other mechanism initiates star formation.
