Being on the other side of the Sun and orbiting in complete opposition to Earth. The twin could than exist out of sight of the human eye or the telescope.

Postulation, hypothesis, conjecture, proof, an unproven idea may have several stages before it become scientific facts.

It is known that no twin earth exists in the same orbit, on the completely opposite side of the sun.
However, the twin/evil earth theory has lasted for centuries, and at one point it was taken to be scientific fact that there was atwin planet, but the observations were probably just those of venus. Obviously, this idea did not last long.

No. It is not a matter of opinion as other answerers would seem to state. Such an orbit is mathematically impossible. It is termed a Lagrange point after the works of Josef Lagrange. The orbit would become gravitationally unstable. Also, perturbations towards the other planets such as Mars and Venus would be noticeably measureable. The effect is termed phase shift variance and such a shift has not been seen.
I understand that the question is theoretical. The answer is no, it is not and could not be possible.
One can find websites which state that such a planet exists and this is kept secret by NASA. However, such sites will always be presented by kooks and one would find it best to avoid them.

That is impossible because it is dynamically unstable. Any planet in Earth's orbit would drift slowly away from the opposite side of the Sun to one of the stable Lagrange points 60 degrees behind or ahead of Earth where it would remain in plain sight.

Yes, I remember that movie too. The title escapes me.
The planet was discovered after a probe going around the Sun sent pictures back to Earth. Then they send a space ship but the lander crash and the pilot is rescued thinking the crashed back on Earth. It turned out the other Earth was a mirror image of the first, people and all. When the guy tries go return to his Earth during docking with his spaceship the polarity of both spaceships is different which cause the ship to crash again.
Any one remember the title of this movie?

No. We DO know what is on the opposite side of the sun as we have sent plenty of probes to other planets that would have seen a whole other planet on the other side of the sun had there been one.

Such an orbit is possible but the odds against such a thing are immense. We know there's no such planet too because we've imaged the inner solar system many times from deep-space probes. Take a look at the "Portrait of the Solar System" at this website http://solarviews.com/cap/misc/vgr_fam1.htm

First of all, the chances of that happening are so small that there's no point in even thinking about them, and second of all, if there was one, space probes would have found it by now. But seriously, the factors, ie. speed, distance, size, etc. would pretty much never be the same, and it would never be identical.

No, the "twin earth" orbit is unstable. Nothing could orbit there.

Yep - I saw the movie too... sheesh that was a long time ago. "Journey to the Far Side of the Sun".... Doppelganger movies.
Even at the tender age of 7-ish, I thought it was contrived :-)

No. You see we know what's on the opposite side on the sun. Think about it.
