Comparative Life Zones
March 4, 2009
In astronomy a habitable zone (HZ) is a region of space around a star where conditions are favorable for life as it may be found on Earth. Planets and moons in these regions are the likeliest candidates to be habitable. Our Sun has a temperature of about 5800K. For stars cooler than our Sun, M dwarfs at 3000-4000K, the region is closer in. For hotter stars, A dwarfs at 10,000K, the region is much further out.
