Quizplus · Accepted Answer

The habitable zone, also known as the Goldilocks zone, is the region around a star where the temperature is just right for liquid water to exist on the surface of a planet. This zone depends primarily on the star's mass and age, as these factors determine its brightness and temperature. A star that is too hot or too cool will not have a habitable zone in which liquid water can exist. Radius and distance, color and distance, and luminosity and velocity are also important factors, but their impact on the habitable zone is secondary to mass and age.
