Satellite galaxies of the Milky Way
There are 61 small galaxies confirmed to be within 420 kiloparsecs (1.4 million light-years) of the Milky Way,[2] but not all of them are necessarily in orbit, and some may themselves be in orbit of other satellite galaxies.
One of which is the Sculptor Dwarf Galaxy which
contains only 4 percent of the carbon and other heavy elements in our own galaxy, the Milky Way, making it similar to primitive galaxies seen at the edge of the universe.
