Planet Earth's future replacement

Planet Earth's future replacementEarth was now uncomfortable hot and arid. The researchers also explore the adventure - a new place in space. Have they already found a new residence that will be "Earth" the future?
1. Titan, the Earth's past.
    Owned Saturn this month is 1.2 billion kilometers from Earth.For 2.5 hours of landing in early 2005, the Cassini-Huygens mission took about 750 photos. They found liquid ethane and methane. Water freezes because only the hottest side of -179 Celsius. If there are collisions with other celestial bodies, may be liquid water within a few hundred years. Titan resembles the Earth 4.6 billion years ago, wrapped in a thick orange clouds and atmosphere, have a lot of lakes, valleys and mountains.Unfortunately, the atmosphere is not oxygenated. We need to think again if you will expand to Titan!
2. Gliese 581C, super Earth.
    Planet Earth bermasa 1-10 times called "super-Earth". Well, the mass of Gliese 581C five times Earth's mass. Planet of the libra constellation is located 20.5 light years or about 193 trillion miles. Gliese 581C orbit the sun with temperatures between 00-40 Celsius, Gliese 581C allows to live. The surface is mountainous and covered with oceans. Gliese 581C takes 13 days to orbit. Wow, compared with the Earth around the sun for 365 days!
3. GJ 436c, heat the Earth.
    GJ 436c is orbiting the star GJ 436 is found in the constellation Leo. Finger - finger about 1.5 times the Earth. 5 times Earth's mass, so he also "super-Earth". The distance is about 30 light years from Earth. GJ 436c orbits for 5.2 days and 4.2 days rotates. Calculations, a day on Earth is almost equal to 22 days in GJ 436c. The planet is hot enough, the surface temperature reaches 127-427 Celsius. But the temperature at the poles may be lower, around 77 Celsius. Compared to Earth, there is still much hotter.
Scientists also discovered planets - planets like Earth, such as OGLE-2005 BLG-390Lb and Gliese 876d. But yet there is as powerful as the Earth. Who most deserves to be "Earth" the future? Probably son - our daughter who will find it later!
