Luxterna & Noxterna Zones
Why do they exist?
TRAPPIST-1 e is tidally locked. This is a phenemenon where one side of the planet is permenantly facing the gravitational body its orbiting. Due to the tidal locking, one side of the planet will only experience eternal day, or as we call it Luxterna Zone and the other will only experience eternal night, or as we call it Noxterna Zone
Luxterna
This side of the planet will always be facing the sun, getting constant sunlight. It may rest at the stable temperature of 35°C, making it suitable for plant life to grow and provide resources for any living creatures or the temperature may be too hot for any living creature to live in.
Noxterna
This side of the planet is slightly more chilly than the other, resting at a constant temperature of 5°C. Although it is slightly colder, some species of animals and plants can still survive. However, this side of the planet may also be too cold, to the point where the region is unhospitable.
