> This was the plot of the movie Melancholia. There was another Earth on the same orbit as ours, but we had no idea because it was always on the exact opposite side of the Sun ftom us. Until something happens and the two worlds are set to collide.
That's... not it at all.
Melancholia was a rogue (planet not in orbit of our star or any other star, but flying freely through the galaxy) gas giant (not another "Earth") that entered the solar system without being noticed at first because it entered on the other side of the Sun.
The collision happens because Melancholia enters into Earth's orbital path as it's coming through the solar system - not because it was "always on the same path."
