List of galaxies

Wikimedia list article

List of galaxies and galaxy clusters. Because there are so many galaxies in the universe, this list has been divided into several categories.

The first catalog that catalogues galaxies is the Catalogue of Galaxies and of Clusters of Galaxies.

List of nearby galaxiesEdit

This is list of nearby galaxies to the Milky Way Galaxy, our galaxy. The first four listed below are part of the Local Group of galaxies, a galaxy group containing at least 50 galaxies, including the Milky Way and Andromeda.

List of nearby Galaxies
Image Name Distance Information
  Large Magellanic Cloud 162,980 light years This is a galaxy satellite of our Milky Way, and the prototype for the class "Magellanic type spiral".
  Small Magellanic Cloud 200,000 light years This is a galaxy satellite of our Milky Way.
  Andromeda Galaxy 2,500,000 light years Largest galaxy in the Local Group
  Triangulum Galaxy 3,000,000 light years Second nearest large galaxy to the Milky Way; Third largest galaxy in the Local Group.
  NGC 3109 4,300,000 light years On the outskirts of the Local Group; may be a Magellanic type spiral .
  NGC 300 6,000,000 light years Between the Sculptor Group and the Local Group; might form a gravitationally bound pair with NGC 55 (see below).
  NGC 55 7,200,000 light years Might form a gravitationally bound pair with NGC 300 (see above)

List of farthest galaxiesEdit

This is list of farthest galaxy from Milky Way. Remember, the farther away from a galaxy, the greater the redshift of galaxy. Redshift is when object appear in a red color because the distance is farther away.

Note that the idea that the radius of the observable universe must amount to only 13.8 billion light-years (like the age of universe) is incorrect. Light travel distance (LTD) is time required for light to reach the observer.

(≈) means "almost equal to."

Farthest galaxies
Image Name Distance Redshift
  GN-z11 ≈ 32 billion light years (proper distance)

≈ 13.8 billion light years (light travel distance)

z = 11.09
  EGSY8p7 13.2 billion light years (light travel distance) z = 8.68
  EGS-zs8-1 13.04 billion light years (light travel distance) z = 7.73
