Investigation of the open star cluster NGC 957.
Abstract
The photographic UBV photometry of Johnson and Morgan (1957, 1961) for 250 stars brighter than 14.5 m in a region of the open star cluster NGC 957 is performed. The cluster size, extinction of light in the cluster's direction, the distance, and the cluster age are determined.
