Virgo I

Virgo I is an extremely faint satellite galaxy of the Milky Way.^[2] It was discovered in the Subaru Strategic Survey. Virgo I has an absolute visual magnitude of -0.8 making it one of the least luminous galaxies confirmed thus far. The galaxy has a radius of 124 light years, (half light radius 38 pc) meaning that it is too big to be a globular cluster.^[2] Cetus II is dimmer, but too small to be classed as a galaxy.^[2] Virgo I is dimmer than Segue I, the previous dimmest known. The distance to Virgo I is 87 kiloparsecs (280,000 ly).^[1]
