Our Milky Way has a diameter of 100,000 light-years, and

contains somewhere between 200-400 billion stars. Other galaxies

can have anywhere from about 10 million stars to about 100 trillion

stars; a dwarf galaxy is much smaller than the Milky Way, while the

largest galaxies can have a diameter of several hundred thousand
