The basic answer is NO. The gravitational effects of such a planet would have been noticed on the other planets we know about. Also, if the planet had exactly the same orbit as the earth, it would be visible from the earth periodically because our orbit is not circular: we move faster at some points than at others. A planet in exactly the same orbit would be moving slow when we move fast and vice versa. But, even more, it turns out that a different orbit exactly opposite the earth at all times would be unstable. This follows by applying the known laws of gravity to such a situation. The point exactly opposite turns out to be an unstable equilibrium, so such a planet would be flung away from that position.

Think about it. The Earth's orbit isn't a circle, so the two planets could NOT just sit opposite each other always moving at the same speed. It is an ellipse, so at times (around January) the orbital speed is faster, while the Earth is closer to the Sun, while at other times (around July) the orbital speed is slower while the Earth is farthest from the Sun. The two planets would have to have EXACTLY the same orbital parameters separated by 180 degrees. Doesn't sound very likely, does it? Imagine Halley's Comet, but there is an "Anti-Halley's Comet" too. They both swing into the Inner Solar System at the same time, from opposite directions, swoop around the Sun on opposite sides and (here's the hard part) NEVER get perturbed by any of the planets or any other space junk, for if they were nudged even a little, the whole ballet is called off. Hope that helped.

It is certainly "possible" in a physical sense, but there is no evidence for such a planet. Any object at the same distance form the Sun as the Earth would orbit at the same speed, so if there were a planet directly opposite the Earth in its orbit the Sun would always be in the way, making it impossible to see. However, the existence of such a planet would make itself known by its gravitational effects on the other planets, which are easily observable. Also, it would most certainly have been spied by a number of space missions sent from Earth to observe the other planets in our solar system.

I'm sure that it is possible for there to be a planet in the same orbit, however it is not happening, and I am sure we could see it by now. A planet would have to be traveling the exact same speed as the earth in order for it to be constantly opposite of our position. Since the chances of that are pretty unlikely, it would have gotten closer to us by now. Even if its off just by a little bit, after millions of years it would be getting closer. Also, there have been soooo many telescopes, satellites, etc. launched, that it would be impossible for one of them to have missed another planet.

No. There isn't another planet in the same orbit as Earth.
The Mayan account is part of their myths and legends. How many times must it be repeated that the Mayans were a highly superstitious culture. Their priests sought to control the common people by scaring the hellout of them with eerie accounts. How easily are you controlled, eh?
"MYTH" == A myth, in popular use, is something that is widely believed but false.

That is a good myth and there has even been a movie made of that same subject but no there is no "twin" earth. A space probe would have seen it long before now.
Voyager has taken many pictures of our solar system and all planets have been accounted for and there is no sister earth, sorry......

No. We would see gravitational effects (slight) from Earth on the Earth and other planets. We would also have seen it from any one of several spacecraft that have been lauched and it is likely that we would have seen it from the Moon landings or in transit to the Moon landings

No. We would clearly see the gravitational effects of such a planet. And we've sent plenty of spacecraft out that far that would have spotted it easily.

Nope. We would have noticed its agravitational affect on the other planets nearby. Not to mention we have sent out many space probes and would have seen it.

that is not only imposible but it deffies the fundamental laws of physics. You cannot have more than one planet on one orbit. Period.
