There was a Science fiction movie sometime ago (I do not remember its 
name) about a planet in the same orbit of Earth but hidden behind the 
Sun so it could never be visible from Earth. Turns out that that planet 
was the exact mirror image of Earth and all its inhabitants looked like 
the Earthings with the difference that their organs was in the opposite 
side like the heart was in the right side instead in the left and they 
would shake hands with the left hand and so on...
