The period of 0.267394 days determined through analysis of photoelectric observations of the HD 200925 in the standard UBV system, together with the shape of the light and color curves, suggests that the star is a dwarf Cepheid. The mass derived along with other physical parameters of the star is found to agree with the value inferred from the evolutionary tracks, and a post-Main Sequence star in the hydrogen shell-burning stage of evolution is implied by the data. An F2 III spectral class is assigned to the star.
