I remember in Law class during current events someone said that people found a planet like earth. Hmmm, i've been reading other answers from question like this and everybody says, there is no planet like earth, or it's possible. So who's right?
Oh n i don't see the kid or the teacher anymore because i don't go to that school anymore.

the planet is called Gliese-581 C

(A would be the star, b the next planet and c the second planet)
they claim its in the right distance from the star to maintain temps close to what the earth has and they claim it has water.
also the size is very close to that of earth's
thats about it. they wouldn't truly be able to tell if it was "like" earth unless they landed on the planet.
as far as like goes, "like" is a general term often misused and misunderstood.
Jupiter is a planet like earth, meaning it IS a planet.
also you might go as far as to say that it is almost perfectly spherical and has an atmosphere, "like" earth.
true, no planet could be exactly "like" earth, just like no other human can be "like" you. get it?

You might like to consider how long an earth-like planet may typically exist for. True there are gazillions of stars in our galaxy alone, and it would appear that many of them have at least a planet or two, occasionally one being the size and composition of earth.
However, if an earth-like planet was to form somewhere, it is likely it would be clobbered by other planets, asteroids or other calamity long before any breathing, ambulating lifeforms managed to develop very far.
It is entirely possible that our own earth is an exceedingly rare planet indeed in that it has remained life-friendly for such a long time.

they were probably talking about Gliese-581. It may have two planets inside the habitable zone. That doesn't mean they're exactly like Earth or that they have life. But they *might* and that's kind of exciting.
We need bigger telescopes!

No.
We haven't discovered any planets similar to earth yet.
But I wouldn't be surprised if there were millions of earth-like planets in our universe alone.

Think of it like this.
Wait till its a clear night, and look up at they sky.
Every single dot of light that you see is a star, either like our sun, or at other various stages in their life cycle.
Around every one of thoes suns will be planets.
(And theres more stars in they sky than there are grains of sand of the planet)
Mathematically its higly improbable that our planet will be the only one that supports life.
(But if it was, how weird would that be..................?)
