It's not only temperature, presence of water and distance to star. It's also a large variety of factors. For instance... what is the atmospheric pressure? boiling point of water is affected by atmospheric pressure. Even if temperature is low, if atmospheric pressure is also low, water would boil at a lower temperature. In Mars for instance, water boils all the time. Some people might say you can probably create more atmospheric pressure by terraforming the atmosphere. But not all planets can retain an atmosphere. Solar activity, planet magnetic field and gravity can affect that. Then, gamma ray exposure. Radiation can sterilize a planet. It would be good to measure what is it like there.
