The planet (Gliese 581D) was discovered using the HARPS instrument on the European Southern Observatory 3.6 meter telescope in La Silla, Chile.
It was discovered on 24 April 2007 by the team of Stéphane Udry of the Geneva Observatory in Switzerland.
You can't. Perhaps your grand children or great grand children or maybe great great grandchildren might. At he moment, March 08, 2015, even though it is possible to design an engine that would get a craft to something 20 light years away, there is no technology available that would let living organisms get there. Science fiction offers many possibilities, but hey are - so far - just ideas that can not be engineered at the moment.
It was discovered by a team of scientists at an observatory in Chile on April 24th, 2007.
Steven S. Vogt et al. discovered Gliese 581 g.
The temperature is not precisely known. If you read the Wikipedia article on Gliese 581 c, you'll find various estimates, based on different methods.
Gliese itself does not exist, but Gliese 581 is a red star.
Gliese 581 c is too hot for life because it is closer to its star. This planet is similar to venus. This planet traps too much heat that causes a strong greenhouse effect. The temperature is too high and the atmosphere is nearly all carbon dioxide. Gliese 581 d is at the right distance for liquid water to exist. It is at the Goldilocks zone just like the earth. That means life could exist on Gliese d. This planet have the right temperature. It has a magnetic field and a rich oxygen and nitrogen atmosphere.
No. g liese 581c is a planet that orbits a star, Gliese 581.
gliese 581 is a star system not a planet however two of the 3 planets there are debatable that one of them could support life
Gliese 581 g was discovered on September 29, 2010.
Gliese is a new planet discovered in April 27, 2007 but told in 2010.
3-6. The 3 planet model would have gliese 581 b too hot, gliese 581 c in the habitable zone, and gliese 581 d too cold. The 6 planet model would have gliese 581 e, b, and c too hot, gliese 581 g and d in the habitable zone, and gliese 581 f too cold.
Earth is similar to Gliese 581 c, in that they both are the third planet from their sun. See related links for information about Gliese 581 c.

12,000 miles in diameter
Gliese itself does not exist, but Gliese 581 is a red star.
Otherwise known as Zarmina's world, Gliese 581 G is apparently of the condition to sustain life. It is an estimated 20.3 light years away. It orbits around a red dwarf called Gliese 581. For more info check out the related link
Planets are simply named by adding a letter to the host star name. The first planet found orbiting GJ 581 is called GJ 581 b (where A corresponds to the star). The 2nd discovered planet is GJ 581 c, and so on.
The most likely candidates are (in no order): Gliese 581 g, HD 40307 g, Gliese 163 c, Gliese 581 d, Tau Ceti e, Gliese 667C c, Kepler 22 b, HD 85512 b and Tau Ceti f
Gliese 581 c is too hot for life because it is closer to its star. This planet is similar to venus. This planet traps too much heat that causes a strong greenhouse effect. The temperature is too high and the atmosphere is nearly all carbon dioxide. Gliese 581 d is at the right distance for liquid water to exist. It is at the Goldilocks zone just like the earth. That means life could exist on Gliese d. This planet have the right temperature. It has a magnetic field and a rich oxygen and nitrogen atmosphere.
Gliese 581 IS the system, D is the planet.
