Trisolaris

Trisolaris is a planet located within the Alpha Centauri star system, approximately 4.21 light-years from Earth. Trisolaris is part of a three-body system consisting of Trisolaris and two stars. This unstable system results in irregular cycles alternating between extreme heat/cold and a comfortable environment conducive to life, referred to by the Trisolarans as Chaotic Eras and Stable Eras, respectively.

Inhabitants
Trisolaris is inhabited by a sentient race called Trisolarans. Trisolarans communicate by expressing their thoughts using visual light. As a result, it is not possible for Trisolarans to lie or keep secrets.
