The Taranis system is an unclaimed planetary system that consists of an A-type main sequence star, a mesoplanet, two terrestrial planets, a gas giant, and two asteroid belts.
Discovered in SEY 2478 by the United Nations of Earth (UNE) survey ship Mythic Horizon, the initial scouting report classified its planets as high-risk candidates for terraforming and the system was left largely untouched. During the Messer Era, Taranis was sometimes used as a testbed for new technology, which led to a 2566 accident that destroyed the moon of Taranis II. In addition to the dangerous debris field created by this incident, the system's two dense asteroid belts pose a persistent navigational hazard for travelers.
