1Milky Way Galaxy0This is our galaxy, we are part of it.
2Omega Centauri0.0183 Mly
3Canis Major Dwarf0.025 Mly
4Virgo Stellar Stream0.030 Mly
5Sagittarius Dwarf Elliptical Galaxy0.081 Mly
6Large Magellanic Cloud0.163 Mly
  • Mly represents millions of light-years, a measure of distance.
  • Distances are measured from Earth, with Earth being at zero.

Sagittarius Dwarf Elliptical Galaxy1994 − 20030.081 Mly
Large Magellanic Cloudantiquity − 19940.163 MlyThis is the upper bound, as it is nearest galaxy observable with the naked-eye.
Small Magellanic Cloud1913–1914This was the first intergalactic distance measured. In 1913, Ejnar Hertzsprung measures the distance to SMC using Cepheid variables. In 1914, he did it for LMC.
Andromeda Galaxy1923This was the first galaxy determined to be not part of the Milky Way.
  • Mly represents millions of light-years, a measure of distance.
  • Distances are measured from Earth, with Earth being at zero.

  • Omega Centauri does not appear on this list because is not currently considered a galaxy, per se, it is considered a former galaxy, and all that remains of one that was cannibalized by the Milky Way.
