A galaxy is, by definition, any large collection of stars that can be recognized as a separate physical. In terms of number of stars,dwarf irregular galaxy a little like the Small Magellanic Cloud has about one billion stars in it, but there are even smaller systems that are recognized as galaxies such as Leo I and II dwarf galaxies withabout 1 million stars in them, and Draco system with hundreds of thousands of stars in it. 


The largest star cluster, a globular cluster Messier 15 called about 6 million stars, so we see that for small galaxies, there is a fuzzy set of what we mean by a galaxy and a large cluster. In addition to their mass and number of stars, a galaxy is a collection of stars and gas moving through the universe, regardless of the Milky Way. Globular clusters are swarms of stars round the orbit of the Milky Way, while Leo and Draco Systems seem to be independent collections of stars.


Many galaxies also continue to train new generations of stars. The Milky Way and all spiral galaxies in the shape of it , to produce new stars at a rate of one or two stars per year. These stars are formed in the vast interstellar clouds which accounts for about 1 to 10 percent of the mass of these galaxies. Globular star clusters, on the other hand, are not currently forming stars because the activity that happened billions of years ago and then stopped once all the clouds of gas and dust were used.
