The planets name is Etriom Four Because its the fourth planet in the solar system. As you can see it has an atmosphere but it has no oxygen. But water....Lots of it. This world has no land. Good luck trying to "mine" here. Well you can sort of mine the water you'd then electrolyse the water to extract the oxygen and hydrogen including deuterium. Deuterium is an isotope of hydrogen. If you were wondering. #Blue #Waterworld #Moon #Atmosphere #Barren #Planet #Stars #Light #Realistic
