Abstract

Abstract—Based on archived images from the Hubble Space Telescope, stellar photometry of the dwarf galaxy Coma P, located near the Virgo galaxy cluster, was performed. The selection of weakly luminous regions of the galaxy showed that Coma P consists of two interacting dwarf galaxies, one of which has a weak star formation, and the second galaxy has a very low surface brightness, there is no star formation in it, and it can be called a “dark” galaxy. The distance to this pair of galaxies, measured by the TRGB method (D = 12.7 ± 0.9 Mpc), showed that Coma P is located on the periphery of the Virgo galaxy cluster.
