　　The habitability of planets has received increasing interest in recent years, in particular in view of the increasing number of detected extrasolar planets.Planetary habitability (for life as we know it) is usually thought to require water on (or near) the surface and a sufficient supoly of energy and nutrients.The request for water on the surface leads to the concept of the habitable zone where stellar radiation and atmosphere greenhousing keep the surface temperature within the stability range of liquid water.
