A minor planet located in the Sirius system, 8.7 light years from Earth. Gravitational interference from Sirius's binary companion prevented the planet's discovery by Earth until A.D. 2021. Its atmosphere and environment closely match those of Earth, and it had long been investigated as a potential candidate for terraforming. Once interstellar travel became a reality, it was chosen as Earth's first colony planet. Unmanned exploration reports turned up no signs of dangerous creatures or intelligent life, and the environmental samples examined revealed no harmful elements or unknown viruses, leading early researchers to dub the planet "Second Earth."
