摘要：

Sophisticated optical astronomy projects such as the Sloan Digital Sky Survey are reaching a new threshold in detecting the least luminous galaxies in the Universe, and now at least twenty-three faint satellite galaxies are known in the region of the Milky Way. They range in luminosity from about a thousand to more than 100 million times that of the Sun. The velocities of the stars in these galaxies reveal that despite this variation in luminosity, each of the galaxies is similar in mass, at about 10 million times the mass of the Sun within their central 300 parsecs. The faintest of the Milky Way satellites are accordingly the most dark-matter-dominated galaxies known in the Universe.
