What is the difference between Gliese 581 c and Gliese 581 d?
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.
How many planets does Andromeda galaxy have?
At present there are 350 extrasolar planets. Most are contained in the Milky Way galaxy. They are primarily "gas giant" planets, but if our solar system is typical (the Law of Mediocrity would lead us to believe it is) there should be many more rocky planets like ours.The extrasolar planets discovered in our neighbouring galaxy, Andromeda, are: * Upsilon Andromeda b (AKA: HD69830 b)* Upsilon Andromeda c (AKA: HD69830 c) * Upsilon Andromeda d (AKA: HD69830 d) * HD 8673 bAgain, if our galaxy is normal, then Andromeda would have planets around 10% of it's sun-like (G type) starsAside: The "Law of Mediocrity" states that you're nothing special. If you can do it, likely a lot of people can.Update 2009: Newest extra solar planets are Gliese 581 (the closest in size to Earth, only 1.9 times larger) and Gliese 581 (even larger), but it's sitting square in the habitable zone, where liquid water would be possible. Both Gliese 581 d and Gliese 581 e are located in constellation Libra and orbit around Gliese 581.
How strong is the gravity on Gliese 581c?
If it is a rocky planet with a large iron core, Gliese 581c has a radius approximately 50% larger than that of Earth. Gravity on such a planet's surface would be approximately 2.24 times as strong as on Earth. If Gliese 581 c is an icy and/or watery planet, its radius would be less than 2 times that of Earth, even with a very large outer hydrosphere. Gravity on the surface of such an icy and/or watery planet would be at least 1.25 times as strong as on Earth.
Who discovered the gliese 581 c?
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.

The family of candidate habitable planets was extended in late September 2010 to include Gliese 581 g, a tidally locked planet in the middle of the habitable zone, and currently the most likely discovered exoplanet to be capable of supporting life.
How many planets does gliese 581 have?
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.
What is the atmosphere of gliese 581 c?
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.

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.
What is Gliese 581 c?
Gliese is a new planet discovered in April 27, 2007 but told in 2010.
What size is the planet gliese 581 c?
12,000 miles in diameter
Is there another planet that you could live on?
There are planets that are good candidates. There called Gliese 581 c and Gliese 581 d, they orbit a red dwarf 20.3 light years away. And they are thought to have an atmosphere and a temperature in which water may exist, and may also be in the "Goldilocks Zone."
What is Gliese 581 g?
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
What known exosolar planet confirmed within the inhabital has had the highest calculated probability of supporting life?
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
Which planet apart from earth may have or had life as you know it?
No other planet in our solar system could support advanced life such as on Earth. Others could support UNintelligent life. Planets in other galaxies that may support life are: OGLE-2005-BLG-390Lb , Gliese 581 c, and Gliese 581 d.
What qualities earned planet Gliese 581 g its nickname?
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.
Can the planet Gliese 581 g support life?
Gliese 581 is a red dwarf star that is around 20.5 light years from ours. Up to six planets have been detected in orbit around this star Gliese e, b, c, g, d and f. The fourth one out (Gliese 581 g) is thought to be the most Earth-like planet found so far, if it were to be a rocky planet. It is the right distance from its star in terms of ideal temperature (for liquid water). It is 3.1 to 4.3 times more massive than the earth. It was discovered in September 2010, but is still to be confirmed. It is possible that this planet may harbour life, but the exact surface conditions cannot be confirmed precisely enough to say for sure.
How far is gliese 581 c form the sun?
The star Gliese 581 is a red dwarf star, 20.3 light-years away. Recent observations indicate that a number of planets orbit this star, including at least one of approximately Earth's mass that astronomers say may be within the habitable zone, meaning that the temperature of the planet's surface may - MAY - allow water to exist in a liquid state. It's important to remember that much of the speculation about Gliese 581g is EXTREMELY speculative. We don't know what sort of surface the planet might have, nor anything about the atmosphere; the ONLY things we know even approximately are the mass and the orbit. At a first glance, it might seem like this could be a potentially habitable world - but notice all of the weasel-words that I used. We don't have ANY idea of the conditions there.
