Exoplanets: The Next Stop for Human Future Settlement

The traditional planetary science faced challenges upon the discovery of thousands of planets which are not same as the planets present in our solar system. These planets which are outside our solar system are called as exoplanets. These planets are different as they revolve around stars and not the sun. The search and discovery of exoplanets has changed our perspective, understanding of the cosmos, and have given us new hope to find a habitable planet other than the earth. Exoplanets are very interesting to study, are also very diverse in terms of their size, temperature, atmospheres, and their distance from earth. Scientists are observing and monitoring the exoplanets from various ground observatories that gives them unprecedented opportunities to probe and study the atmosphere and surfaces of potentially habitable exoplanets for existence of life. Different kinds of problems will arise in future as we go further in exploring these exoplanets, for this many advance technologies are being developed by different space organizations. In this paper we are going to study a viable list of exoplanets and select the best one for hosting life. The benefits of settling life on other planets is also discussed. The scope of this paper also includes a comparative study of the temperatures, atmospheres of various exoplanets to identify a suitable exoplanet for future life settlement.
