Abstract
ABSTRACT The paper discusses recent and continuing studies of the outer halo of our galaxy. A brief inventory is conducted of the stellar systems lying at distances exceeding 25 kpc from the galactic center. The spatial distributions of such systems and the field stars are reviewed, as well as the galactic mass estimates that follow from considerations of their kinematics. The question of a gradient in the halo's metallicity is addressed, plus the scant information available on the chemical abundance pattern of outer halo stars. Finally, the probability of differences in ages of outer halo systems is discussed.
