Point of origin

The point of origin is a symbol neccessary for Stargate addresses. While the first six symbols represent constellations indicating a point in space, the seventh tells the Stargate where the wormhole is coming from.

For years, Earth's point of origin was unknown, as the Egyptians had placed to figures praying by the symbol of the pyramid. Daniel Jackson eventually reacized the mistake, and the Tau'ri were able to link to Abydos. After arriving on Abydos, Jackson had difficulty locating the hlanet's symbol, but eventually found it.
