The Pegasus Galaxy is a fictional location in the Stargate Atlantis universe. Its location is based on a real galaxy called Pegasus Dwarf Irregular Galaxy. It is significantly smaller than the Milky Way. The Galaxy is 3 million light-years from Earth. Currently, the quickest way to get there is to go through the Intergalactic gate bridge built by the SGC and Atlantis. It takes about a half hour to get from one side to the other. Without this bridge, the only other means is by ship equipped with intergalactic hyperdrive engines or through the Stargate directly from Earth to the Ancient city of Atlantis. Unfortunately, this more direct route through the stargate requires power that can only be supplied by a ZPM.
