Kepler 22b is a planet with all liquid, water. gliese 581g is a planet that might be consists of land and water + their distance from earth.
As far as we currently know, it is Earth. But earth may in fact not be the only planet able to harbor life. We have just begun looking.
A new Earth like planet Kepler 22-b was discovered in 2009 but only recently confirmed as a planet. Its made big news as it is thought to be around 2.4 times the size to Earth and orbits a star that is similar to our own star (the sun) around 600 light years away. More importantly though, it is in the habitable zone, orbiting just the right distance from its star to allow for water to occur in liquid form - essential for life as we know it. There is a lot that we don't know about it as it is so far away, we don't even know what its atmosphere is like or even if it has one, which is also essential to life.
Gliese 581-b is the earth like planet although its about the same size as Jupiter its conditions there are very similar In the future we hope to find more smaller planets the size of earth we cannot find smaller planets because our telescope aren't powerful enough made by a 12 yr old its true im not lieing!!!!!
There are several satellite projects searching for new extra solar planets, and discoveries are being made every month. Since all of the stars that these planets orbit have a catalog designation or a name of their own, the new planets are being given a letter (starting with b, then c.) to follow the name or number of the star. The discoveries of new planets by satellite projects are being give the name of that project, but still only a letter after the satellite project's name. example: COROT 1 b. In our own solar system, there are four new dwarf planets: #5 - Ceres #11 - Haumea #12 - Makemake #13 - Eris.
Although there are a few planets similar to Earth's gravity, atmospheric pressure, temperature, size, etc. Mars is the planet that is most like Earth. Long ago, it was believed that Mars harvested water, just as Earth does now. Mars also has a little over twenty-four hour days and the rotation is much like Earth's.
Gliese 581g
The cast of Gliese 581g - 2013 includes: Ashley Clarke as Laurie Cean Okada as Trin
Yes mostly orbiting a red dwarf gliese 581g (pronunciation "gliza" 581g)which is orbiting a star gliese 581 a red dwarf located 22 light years. and another planet probably called as (earth' cousin) the first earth sized habitable planet called kepler186f located 490 light years orbiting a red dwarf kepler 186
yes gliese 581g has bacteria alians and humans could live there too. You can build a spaceship i your lifetime.
Astronomers have newly discovered a planet , Gliese 581g, within the "Goldilocks" zone - see related link to the news article .
Gliese 581 is located in the constellation Libra. It is a red dwarf star with multiple planets, one of which, Gliese 581g, was once considered a potentially habitable exoplanet due to being in the star's habitable zone.
theoretically yeah 'Gliese 581g is in the 'Goldilocks zone' of its solar system, where liquid water could exist, and is a strong contender to be a habitable world' it orbits around a red dwarf star called Gliese 581 and is 20 light years (over 117 trillion miles) away.
Gliese 581g lies in a zone called "the Goldilocks zone" or habitable zone [See related question]. It's an area in a planets orbit, where liquid water is likely to occur and thus harbour life. It's not too hot or too cold. (As in the porridge) It can also refer to a planet that is close to the size of the Earth.
As far as we currently know, it is Earth. But earth may in fact not be the only planet able to harbor life. We have just begun looking.
it falls in the habitable zone of its star, it has oxygen in it's atmosphere, and it has water. Those are the seeds of life and Gliese 581g most likely has them all! The only bad thing about it is that this planet is tidally locked. It's always day on one side, always night on the other.
yes
The planet which was found past Neptune and is 1 1/2 times the size of Pluto has been given a temporary name 2003 UB313. A permanent name has been requested of the International Astronomical Union but hasn't been released yet.
