Another Earth just like ours is it possible?

Question

imagine that right now there is another world, on the other side of the sun that has people living on it just like us but who have develop completely different. Do you think its possible?

Answer 1

Yes, it is possible, but in other solar systems. Up to now we have discovered more than 200 extrasolar planets in other suns. One with almost the same conditions of the Earth is possible, but we will see for sure when we build more precise sensors.

Answer 2

I saw that movie too. The astronaut who landed on the other planet thought that he had come home because it was exactly like as Earth except everything was in mirror image. Silly movie.

Such a planet would have been discovered simply because it would stray from a perfect conjunction with the sun. The Earth's orbit isn't perfectly circular; it's an ellipse with an eccentricity of 0.01672. Another planet in the same orbit, but differing in mean anomaly by 180 degrees, would differ in TRUE anomaly by 180 degrees ONLY when the two planets were at opposite apsides. After that, the planet that had been at perihelion would swing around the sun faster than the planet that had been at aphelion, meaning that the sun would no longer be exactly between them. The maximum angular separation of the other planet from the sun would be about two degrees. That's four solar diameters. Astronomers who study the sun's atmosphere occlude the photosphere in order to see the corona, and they would probably have noticed the anti-Earth at some point.

Answer 3

It's all in the individual believes. This requires some indepth understanding.
If you believe on todays research then it is possible. If you believe in some of the ancient astrology (like Indian) then it is not possible.
This doesn't mean that the reaserchers are fake.
For me, I believe very strongly on the Indian astrology. Those has been drafted out thousands of years back with very precise calculations (calculations that involve distance between each of the planets and the solar system). It is quiet impossible to derive at during those days. Those calaculations can tell precisely when & what time & where the next eclipse will happen. But today's scientific numbers come out a few weeks or days before.
I did come across that this Indian astrology says, there are no living things other than on earth and they'll never make it.

Answer 4

Your question has two parts...

A.) Could there be another planet somewhere very close to the equivalent of the Earth? The answer to that question is YES. With 200 Billion Plus stars in the MILKY WAY GALAXY just like our Sun, each of those stars could have a solar system of planets (from 0 to 10) and their associated moons. With that many possibilities the likelyhood of one or more being Earthlike is quite high.

B.) Are there people living on that Earthlike Planet just like us? Probably not. Given the total number of species of Insects, the total number of species of Fish, the total number of species of Reptiles, compared to the total number of species of Mammals (of which Mankind is just one), the probability that the circumstances which combined to produce a very large brain in Man would occur elsewhere is very low. HOWEVER, given the total number of various other species, there is nothing to suggest that high intelligence could not happen in insects, fish, or birds. The Octopus in the fish world is extremely intelligent, as is the Dolphin. The Preying Mantis in the insect world is a verry cunning hunter and fears few adversaries. Possibly the unusual quirk that brought about the large brain development in humans will occur in fish or insects somewhere else. We will never know until we go there...

The chance that we have mirror images of people sitting at home watching Channel 9 Television on their Sony TVs is highly unlikely, and I can almost promise you that they don't have Walkmen, IPods, Windows 2000 Software, and XBoxes either.

What is more to the point is that the Earth is some 4.5 Billion Years old. Of those 4.5 Billion years in age, mankind has only had a significant impact for maybe the last 1000 years or so.

4,500,000,000 divided by 1000 = 4,500,000

So mankind's part of the whole epic of Earth is
1 / 4,500,000 of the total time, just a teeny little slice of time.

Given we find another Earthlike planet, who is to say that we will fly by, or land there in just the right teeny slice of time whatever it might be for that planet? More likely we will find that intelligent life forms (what ever those are) have not developed yet, or have already developed and been totally wiped out by some horific natural event (massive volcanic action, asteroid collision, or a possible global disease.

It would just not make sense to propose that the exact string of events that brought about the development of human beings might happen exactly in the same order and proportion somewhere else, light years away. Note that the nearest star to us (other than our Sun) is 4.5 Light Years away.

Answer 5

There is a possibility (high) that there might be a planet similar to earth but the possibility of that planet being on the other side of the sun in v v v low!

Answer 6

there is not any danger a planet orbits the solar in our orbit on the different area of the solar. Our orbit isn't precisely a similar each 3 hundred and sixty 5 days - the gravitational consequence of the solar (that's at one concentration of an ellipse, no longer interior the acceptable centre of a around orbit), the gravitational consequence of Jupiter, Mars, and Venus might all reason that different planet's orbit to get out of synchronization with Earth in an somewhat couple of minutes (possibly one million years or so after formation). we don't might desire to show screen the different area of the solar - orbital mechanics and physics makes it impossible for there to be a planet there.

Answer 7

Not possible on other side of our sun. We know this for sure.

But possible and very likely, but no evidence yet, we have been searching for it. We spend million of Dollar to find the answer but as far as we know we have not encountered any thing.

People do report the encounters but they fail to materialise.

Answer 8

Such a world would have been discovered looong ago by spaceprobes that has gone to the otherside of the sun, from our vantage point, on their way to Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune,

Answer 9

Yes but not on the other side of the sun.

Answer 10

We can only hope it's not like ours! Hopefully they haven't destroyed their planet through greed and power. But what I'd like to know is what the government is planning to do about it. Are they going to send probes and one day spaceships to conquer it and steal their oil too? We've got enough problems on our world to be worrying about life on another!
