From hot to habitable worlds

Terrestrial planets within the habitable zone (HZ) of their stars can now be found with current observing methods (radial velocities and transits). For instance the red dwarf GJ581 hosts at least one potentially habitable planet: planet 'd', which could host stable oceans despite very exotic characteristics compared with our own world . Observations have also revealed that short period planets of a few to ten Earth masses with no equivalent in the solar system are common around G-K-M stars.
