We report the discovery of a new , low luminosity star cluster in the outer halo of the Milky Way .
High quality gr photometry is presented , from which a color-magnitude diagram is constructed , and estimates of age , [ Fe/H ] , [ \alpha /Fe ] , and distance are derived .
The star cluster , which we designate as Kim 2 , lies at a heliocentric distance of \sim 105 kpc .
With a half-light radius of \sim 12.8 pc and ellipticity of \epsilon \sim 0.12 , it shares the properties of outer halo GCs , except for the higher metallicity ( [ Fe/H ] \sim - 1.0 ) and lower luminosity ( M _ { V } \sim - 1.5 ) .
These parameters are similar to those for the globular cluster AM 4 , that is considered to be associated with the Sagittarius dwarf spheroidal galaxy .
We find evidence of dynamical mass segregation and the presence of extra-tidal stars that suggests Kim 2 is most likely a star cluster .
Spectroscopic observations for radial-velocity membership and chemical abundance measurements are needed to further understand the nature of the object .
