The Rhetor system is a planetary system in the United Empire of Earth (UEE) that consists of a G-type main sequence star, a mesoplanet, three terrestrial planets, and a gas giant. Discovered in 2287 by PhD students Neil Nyemeto and Leona Sono from the Martian Institute of Space Technology (MIST), their decision to share their discovery with MIST's president Adrianne Zemlock led to Rhetor becoming a system that is dedicated to education rather than corporate interests. Persei is a center of public education and private research institutes, and some of the most prestigious universities in the UEE are located on Reisse and Mentor.
