A galaxy is a huge gravitationally bound system of stars, interstellar gas and dust, plasma, and (possibly) unseen dark matter. Typical galaxies contain 10 million to one trillion (107 to 1012) stars, all orbiting a common center of gravity. In addition to single stars and a tenuous interstellar medium, most galaxies contain a large number of multiple star systems and star clusters as well as various types of nebulae. Most galaxies are several thousand to several hundred thousand light years in diameter and are usually separated from one another by distances on the order of millions of light years.

Nobody is sure exactly how many galaxies there are in the universe. There are likely to be billions, trillions, quadrillions... And more and more are being found all the time.

I think I heard that there are hundreds of billions of galaxies...more galaxies than there are stars in the Milky Way, or something like that.

Nobody really knows as we have not been able to reach the edge of the universe with our telescopes

I'm sure we'll never know. The universe is seemingly infinite.
