Sentences with phrase «planetary habitability»
"Planetary habitability" refers to the conditions and features that make a planet suitable for life to exist and thrive. It includes essential factors like having a stable climate, presence of liquid water, and the ability to sustain the necessary resources for living organisms. Full definition
