Abstract

With achieving higher technologies, and as the population of our planet grows and sources of Earth consume every day, scientists are trying to find an alternative planet to build a second home for mankind. During the last decades, Mars seemed to be the first planet as a candidate for second home of human. Nevertheless, a few years ago a new planet has been discovered to be suitable for human life. Titan, Saturn’s moon, in spite of its great distance from the Earth has been identified as a good candidate for the second home for mankind due to its atmosphere which is a great shield against radiation. Recently, other planets have been discovered which appear to be habitable and suitable for human life. KOI 736.01, Kepler-22b, Gliese 581 c, and Gliese 581 g seem even more Earth-like when compared to Mars and Titan. Hence, the goal in this research is to estimate the thermal life of carbon structures on these planets to determine which planet offers the highest thermal life. Carbon structures have been recently used as aerospace structures due to their excellent lightweight and high strength.

Key words: Carbon structures, thermal life, KOI 736.01, Kepler-22b, Gliese 581 c, Gliese 581 g.
