Dwarf galaxies around the Milky Way

How did a satellite galaxy of the Milky Way come to be?

Crater 2, located approximately 380,000 light years from Earth, is one of the largest satellite galaxies of the Milky Way. Extremely cold and with slow-moving stars, Crater 2 has low surface brightness. How this galaxy originated remains unclear. “Since its discovery in 2016, there have been many attempts to reproduce...
