Gliese 581g a Newly Discovered Planet Like Earth

have you heard about the gliese 581g name before? That's a newly discovered planet which is just like earth. the scientist even said that the Gliese 581g planet might be a habitable planet which has an environment much similar to earth. It also may contain water and even Life.

This planet included into an Exoplanet which is located around 123 trilion miles away from Earth and orbits a star at a distance that places it squarely in the habitable or the Goldilocks zone.

It found that Gliese 581g has a mass three to four time the Earth's and orbits its star in just under 37 days. Its mass indicates that it is probably a rocky planet with a definite surface and enough gravity to hold on to an atmosphere,

The Scientist has made a list of the most livable planets according into ESI (Earth Similarity Index) The index was refers to the size, density and distance to the parent star of the planets that are compared to ours. And with the discovery of this Gliese 581g. here's the new list of the Most livable planet

1. Earth – 1.00
2. Gliese 581g – 0.89
3. Gliese 581d – 0.74
4. Gliese 581c – 0.70
5. Mars – 0.70
6. Mercury – 0.60
7. HD 69830 d – 0.60
8. 55 Cnc c – 0.56
9. Moon – 0.56
10. Gliese 581e – 0.53

I wonder if in the future we can live on the other planet? well i think that is impossible since until now the question such as "How do we get there?" is still have no answers.
