Showalter

Showalter is an Earth-like exoplanet, and the first planet discovered that can sustain human life without terraforming. Showalter's temperature, atmospheric composition, liquid water content, and gravity are nearly identical to Earth's.

Showalter bears simple native plant life, most notably the grass-like tereta that cover its landmasses, though it also possesses several species analogous to algae and moss and some basic unicellular life forms.
