    • found: ESA science & technology: habitable planets, via WWW, July 13, 2005(Depending on the stellar type, habitable planets will be at different distances from the parent star. Firstly, it must possess a thin atmosphere, similar to that of Earth. To do this, the planet must be more than half, but less than ten times, the mass of the Earth ... Secondly, the planet's surface temperature must be similar to Earth's so it is capable of sustaining liquid water)
