The orbit of Gaus was erratic due to its sun which had drifted towards the Solar System and brought Gaus and Earth closer and closer to each other. They were actually sister planets having been formed at the same time from one giant lump of rock, dust, gases and water. The giant spinning mass bulged at the equator from the centrifugal force and finally ripped apart as one section flew away into space. It was unsure of what would happen when the Dimensional Merge would take place.
However, it started as a dot of light in the universe (i.e. like a distant star). However, the dot of light started to slowly increase in size as the days passed. Sonichu as well as the rest of the Chaotic Combo were increasingly concerned.
