Earth 2.0 ... Life Possible On Gliese 581g, 20.5 Light-Years Away
Astronomers at the Keck telescope in Hawaii, during a study that has been underway for more than a decade, have identified a solar system that has a planet they suspect could support life as we know or understand it here on our Oblate Spheroid.
Let's call it Earth 2.0. It is a planet that is circling a Sun named Gliese, that is located a little over twenty light years away (the time it would take to get there if one could travel in a craft at the speed of light and carry enough food and etc. to sustains one's life to arrive and observe this suspect orb on site).

Discovered Planet Zarmina (Gliese 581g) Is 'Habitable' For Human Life
By ryangeneral - Honolulu : HI : USA | Sep 30, 2010
The planet lies near the middle of the Goldilocks zone, or habitable zone of its parent star, and the presence of liquid water is considered a strong possibility. The discovery of Gliese 581 g was announced in September 2010, and is believed to be the first Goldilocks planet ever found, the most Earth-like planet, and the best exoplanet candidate with the potential for harboring life found to date.
The planet was detected using radial velocity measurements combining the data from the HIRES instrument of the Keck 1 telescope and the HARPS instrument of ESO's 3.6m telescope at La Silla Observatory. The planet is believed to have a mass of three to four times that of the Earth and an orbital period of just under 37 days.
Steven Vogt, the co-discoverer, unofficially named the planet "Zarmina", after his wife.

The Goldilocks zone refers to a story that parents read to their children that goes by the formal title "The Story Of The Three Bears". This fable, often referred to as "Goldilocks and the Three Bears" is a children's story first recorded in narrative form by English author and poet Robert Southey and first published in a volume of his writings in 1837. The same year, writer George Nicol published a version in rhyme based upon Southey's prose tale, with Southey approving the attempt to bring the story more exposure. Both versions tell of three bears and an old woman who trespasses upon their property.

In the fable, Goldilocks is hungry and stumbles upon a home of Bears where three bowls of soup or porridge are on the table. Goldilocks helps herself to eating some of the porridge and discovers that one bowl of the food mixture is too hot, one is too cold, and one ... the one she presumably eats all up is ... Just Right!
This planet discovery is in a solar system zone that is just right given our knowledge of the origins of life as we know it here on Earth.
We wonder if the shape of this Gliese 581g orb is the same Oblate Spheroid shape of our own Earth. Welcome Zarmina ... welcome Earth 2.0.
