Gliese 623b

This Hubble Space Telescope picture resolves, for the first time, one of the smallest stars in our Milky Way Galaxy. Called Gliese 623b or Gl 623b, the diminutive star (right of center) is ten times less massive than the Sun and 60, 000 times fainter. (If it were as far away as the Sun, it would be only eight times brighter than the full Moon).
