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.
