Destiny in front of air galaxy

A galaxy is a collection of stars and planets following a circular orbit around a central point. Galaxies can come in groups, including the Local Group. According to Lt. Colonel Samantha Carter, there are hundreds of millions of galaxies in the known Universe. (SG1: "Reckoning, Part 2") However this is a gross underestimation as there are actually approximately between 170 and 200 billion galaxies in the known universe, with newer estimates being 2 trillion.
