Quizplus · Accepted Answer

The habitable zone is defined as the region around a star where temperatures are suitable for liquid water to exist on a planet's surface. This zone depends most on the star's mass and age because these factors determine its luminosity, which affects the amount of energy received by a planet in that zone. A larger, more massive star will have a higher luminosity and a larger habitable zone, while a younger star will have a stronger luminosity and a larger habitable zone. On the other hand, radius, distance, color, and velocity have only minor effects on the habitable zone.
