Galactic Council

This is the group of galaxies that are closest to the Milky Way, representing our local galactic neighbourhood. From a mythological perspective, these would be the members of our local Galactic Council, otherwise known as the Council of Giants*. They are near enough to have gravitationally influenced our galaxy's evolution over the past 13 billion years. The Milky Way is approximately at the centre of this group, which is shaped like an elongated flat sheet (the Local Sheet) about 25 million light years across and 2 million light years thick. Only galaxies with a diameter of about 50,000 light years or greater are profiled here (the Milky Way is approximately 110,000 light years across). Although there are many more small galaxies in this neighbourhood, these are the largest and most noteworthy that have evolved alongside the Milky Way.

* Inspiration for the title "Council of Giants" is from an astronomy paper published in 2014 from York University. More information about this paper can be found here: Council of Giants.
