Terra Nova is a Class M planet located less than twenty light years from Earth. It was one of the first human colonies outside the sol system. Terra Nova was discovered in the late 21st century by astronomers likely working for the United Earth Space Probe Agency. Due to its proximity to Earth, the decision was made to establish a colony on the planet. The success of such a colony was considered uncertain from the start, and the expedition became known as "the Great Experiment". The planet is home to a population of 347,000. The planet was where the surviving Uxali were transported after Earth accepted to transport them to one of their colonies in 2550.
