What primary condition must a planet meet to be considered within the Circumstellar Habitable Zone?
Answer
Maintaining liquid water on its surface
The Habitable Zone (HZ) is defined thermally by the orbital region where a planet with adequate atmospheric pressure can maintain liquid water on its surface, which is considered the fundamental prerequisite for life as we understand it.
