The Local Group is an 'ohana of galaxies that are bound together because of gravity. Among fifty, there are three major galaxies in the local group: Andromeda, Milky Way, and Triangulum. Many more are still unconfirmed.

Edwin Hubble first proposed "The Local Group" in his 1936 book "The Realm of the Nebulae". In it, he initially identified 12 members, including our galaxy, The Milky Way.

​

Within The Local Group exists a form of matter that is called 'dark matter'. It does not interact with light, but influences cosmic structures with its gravitational force.

​

The Local Group contains around 38 confirmed dwarf galaxies. Dwarf galaxies are smaller than galaxies like the Milky Way. They orbit around bigger galaxies and contain more dark matter than visible matter.
