Our Milky Way galaxy is host to 25 smaller satellite galaxies. These satellites are among the least luminous and most dark matter dominated galaxies in the known Universe. However, their number and properties do not fully agree with predictions from otherwise extremely success models of galaxy formation. I will discuss the properties of the Milky Way satellites, including the limits these objects set on the nature of dark matter, and then describe a project to expand the study of satellite galaxies around system beyond the Milky Way.
