Abstract (from CDS):

Observations of the highly isolated dwarf spheroidal galaxy KKs 3 = [KK2000] 03 with the Hubble Space Telescope Advanced Camera for Surveys are presented. We measured the galaxy distance of 2.12±0.07Mpc using the tip of red giant branch method. The total blue absolute magnitude of the galaxy is estimated as MB = -10.8 mag. We briefly discuss the star formation history of KKs 3 derived from its colour-magnitude diagram. According to our calculation, the total stellar mass of the galaxy is 2.3x107M☉, and most stars (74 percent) were formed at an early epoch more than 12 Gyr ago. A full description of the properties of the colour-magnitude diagram requires some extension of star formation in metallicity and age.
