Thegeuse is a terrestrial world with an atmosphere of chlorine and krypton. The surface is mainly composed of silicates with deposits of carbon. Thegeuse has a low mass for its size and is tidally locked to the star Tereshkova-A. The temperature difference between the sunward "hot pole" and the dark side "cold pole" creates constant gale-force winds across the terminator.
Note: This planet can be surveyed for a mercury Heavy Metal Deposit.
