Though one of the nearest neighbours to the Sun in space, the faint star AD Leonis is nonetheless drowned by the light of the second-magnitude giant Algieba or Gamma Leonis. Algieba lies far beyond AD Leonis (more than eight times farther from the Sun, at a distance of 130 light years) but is 50,000 times more luminous than the faint red dwarf in the near foreground.
