there are probably many billions of habitable planets
but for now theres just earth but 40 years ago the star gliese 581 was discovered,4 planets among it
many were 2 hot but 2 were separated from the rest by scientist,both with water
but 1 of those planets were too far out and was vereh cold, and it was only water
so we are left with gliese 581 g, 3 times earths mass
other than that though its earth

Planet:Is there another planet just like the Earth with people like us? Probably not; there are so many possible ways that a planet could develop and life evolve though it's unlikely that it happened exactly the same way twice.
Life:Is there life out there? It is again conjecture, but many many people think this is very likely.
Universe:Is there another universe, perhaps in a "different dimension", similar to ours?
No data exists.. We have no actual evidence that there are any parallel universes, and there is no way that we know of now to test for anything like that.
Other Dimensions:
Given all that, there remain some intriguing issues that give the great scientific minds reasons to wonder whether there are other universes. For one, in the last couple of decades, something called "string theory" has emerged that might describe our universe of 3 space and one time dimension as a slice through a universe that has 12 dimensions. The theory has some broad scientific implications for other theories as an improvement on Einstein's theories for example. Alas, though it is a lovely theory, there has yet been no means of testing it developed. In any case, it has stimulated more questions about universes in "other dimensions."
Other than string theory, there remains the nagging question of the creation of our universe. Even accepting all of the theories around the Big Bang that say the Earth was created out of nothing 13.7 billion years ago, one has no way of saying that other universes were not also created or might currently be being created or might someday just spontaneously erupt in our own universe. So, the reality is we know nothing about this and things can exist that we have never even thought of.

Do other planets have wind like earth?
Yes, but not all. Some planets either evolved without an atmosphere or had their atmosphere decimated by solar wind or gamma-ray bursts. If you are asking are there other habitable planets in the universe - then absolutely. We've not discovered them yet, but there are probably billions, if not trillions of habitable planets elsehwere in the universe, waiting to be discovered.
How likely is it that life exists in other parts of the universe?
Very likely, their are thousands maybe even millions of planets in the galaxy that are habitable, than their are trillions of galaxies.
How many planets are habital?
Other than Earth, no planets have been confirmed to be habitable. We do know of planets in other star systems upon which liquid water could theoretically exist but we can't measure the composition of the planets atmospheres therefore we can't know for certain whether or not they are habitable.
Is there another habitable planet in the solar system?
Earth is the only habitable planet in our solar system. As for the rest of the universe, it's highly probable that there are planets that can sustain life but compared to the billions of other objects in that vast emptiness, it's a difficult task to even find any.

Is the earth the only habitable planet?
For us humans and our animal companions, it is the only habitable planet known to us at the present time. There is a possibility that there are other planets within the Universe that we could inhabit if we could get to them, but the Universe is massive and we currently know very little about the planets within it.
Is there an earth like ours in this universe?
We suspect that there are probably other planets in the universe that could be habitable. It's not likely that there's one EXACTLY like Earth, though.

Very likely, their are thousands maybe even millions of planets in the galaxy that are habitable, than their are trillions of galaxies.

Are alien's real and do they live on their own planet and have stuff like we do?
There are probably a billion stars in our galaxy, and probably a billion galaxies in the universe. We already know what there are planets orbiting many other stars; if there are planets around only 1% of the stars, that's still 100 billion planets. If only 1% of those planets are habitable, that's a billion habitable planets. If only 1% of those planets HAVE life, that's 10 million planets with life. If only 1% of the planets that have life have highly-developed life forms, then there are 100,000 planets with highly developed life forms. If only 1% of those planets have intelligent life, that's still 1,000 planets in the universe that have intelligent life; "aliens". We have NO IDEA if there are any other planets that have life, or intelligent life in the universe, or if those aliens - if any exist - might be willing or able to communicate with us. But I would like to think so.
What are the planets in the galaxy?
There are billions of other planets hanging around in the universe. We're not the only 8 planets in the universe.
Is there any other planets?
How many other planets are there like Earth?
If by "like Earth" you mean habitable (that we could live on, without spacesuits, domes or other technological adaptations): there aren't any in our solar system, and none yet elsewhere that we know of. But scientists keep searching; the universe is a pretty big place, and odds are there are multiple other Earthlike planets out there somewhere.
Why is there no life on any other planets?
This is because it is highly unlikely that the exact circumstances needed to form life will occur. It happened to occur on earth, and that is why it has life. It is theoretically possible for more planets to have life on them. Adding to your answer. Earth is very lucky because it in the habitable zone which means it not too close to the sun and its not too far away. A planet has to be in the habitable to sustain liquid on its surface. They suspect there might be life(single celled) on mars because it is close to the habitable zone. Astronomers have discovered other planets that are in the habitable zone but haven't yet found other life forms.
How many planets of the solar system are at Stargate?
The only planet from our solar system that has been mentioned in the Stargate series is Earth. Other planets do not have stargates, since from the beginning the planets are not habitable.
