The quest for potentially habitable planets is often interpreted as the search for an Earth twin. And yet, some rocky planets outside our Solar System may in fact be more promising candidates for further research. Scientists have run 165 climate simulations for exoplanets that permanently face their ‘sun’ with the same side. They discovered that 2 of the 3 possible climates are potentially habitable.

Most exoplanets orbit relatively small and cool stars known as red dwarfs. Only exoplanets that orbit close to their 3star can be warm enough for liquid water...
