The main governing body of Earth and its colonies is simply referred to as “The Earth Government.” The EG is governed by a single President, a Vice President, a Senate of 16, and 5 Supreme Judges. The government pays for any longevity treatments necessary while a representative holds office. Each President is allowed to maintain longevity treatments after giving up the office to their successor, and Judges are appointed for life.
The Earth Government primarily worries about the needs and concerns of Earth itself, though it is technically the government for the solar system and humanity’s colonies. For this reason, each of the Earth’s colonies, including the Earth itself, are ruled by a Governor who is appointed by the EG.
While there is no law strictly enforcing it, all Presidents and Judges have been born on Earth.
