Trappist 1e (1.19)

Trappist - TRAPPIST-1e is one of seven Earth-sized planets in the TRAPPIST-1 system. About 40 light-years from Earth, TRAPPIST-1 is unusual both for its number of small rocky planets and the number in the habitable zone. Our simulated world has a narrow band of water near the terminator, the divide between a hot, dry day and an ice-covered night side. See this system and more at NASA's website. Use with the WHIMC datapack setting the biome to Soul Sand Valley.
