The Terra system is a planetary system in the United Empire of Earth (UEE) made up of one mesoplanet, one terrestrial planet, two super-Earths, and one G-type star named Terra Nova.
Located at the nexus of seven jump points, the system was first charted in SEY 2516 as part of Project Far Star. It was quickly colonized upon the discovery that the third planet was naturally habitable and that it had one other planet located in the green band. The lush and resource-rich planet Terra (Terra III) became a hub of trade and culture, eventually growing in population and prominence to the point that its government was able to maintain a progressive stance even under the rule of the Messers.
Terra continues to be one of the most influential systems in the UEE. The Transitionalist party, based on Terra III, believes that the system should be the center of the UEE government.
