Galaxies are systems composed of empty space, interstellar gas and cosmic dust. They typically contain anywhere from a million to a trillion stars held together by gravity. But it would be a mistake to see galaxies as solely stand-alone structures. Just imagine a massive gravitational force of billions of solar masses pulling in all kinds of stuff, ranging from small debris to even smaller galaxies! In this journey, you’ll find out how galaxy satellites work and get to know the coolest Milky Way’s neighbours!
The closest satellite galaxies!
