Does somebody heard something about the Earth twin planet, opposite the Sun?

Question

That is very interesting considering that there's some observation dated back in 17th century, so if someone know more about that,

please let me know. I would really appreciate if I'll have an answer from an astronomer. Many thanks.

Answer 1

well we rotate around the sun there would be no oppisit the sun..buy were just one solar system in the galexy there many more galexys out there.... too far awa for the modern day space crafts.... so in a few years a earth twin planet maby be true

Answer 2

It is a total myth.  While observation from the earth of such a twin planet is not possible directly, we have sent out many space probes that would have detected such a planet, and it has not been found.

Answer 3

There is an earth like planet yes in fact I think theres 2

Answer 4

myth

Answer 5

It's not there but it could be observed by the effect its gravitational field has on the other planets and objects in the solar system. However romantic the idea is it is statistically highly unlikely that there would be an identical planet in the same orbit as Earth exactly out of phase with it. But nothings impossible so there may be a planet with another twin in another system somewhere in the universe.

Answer 6

There is no such thing as a "Earth twin".  Any planet in Earth's orbit on the other side of the sun, would change the orbits of Venus and Mars so much, that we could detect the change very easily.  And also, we have sent long-range space probes across the solar system, and they would have seen anything like a Earth twin -- but they haven't.

If the "Earth twin" is on the opposite side of the sun, how could anybody on Earth see it, in the 17th century or any century?

Answer 7

No planet in the solar system is opposite the Sun, as all bodies rotate around the Sun (as it is the heaviest object in the solar system). And these bodies are well known to us now, with four terrestrial, inner and Earth-like, rocky planets: Mercury, Venus, Earth and Mars. There are no other rocky planets within the asteroid belt between Mars and Jupiter.

Sometimes Venus is described as Earth's twin, because in terms of mass, size and composition they are similar (though climatologically and tectonically they are completely different). Perhaps this is what you've heard about?

Don't be disappointed though - one of the exciting parts of astronomy at the moment is the search for Earth-like planets in other solar systems, orbiting other stars than the Sun. Watch that space, because I'm sure over the next few years some exciting discoveries will be made. ;)
