The planets each orbit the Sun at different distances, and they each take different amounts of time to do this. So a year on Earth takes 365.25 Earth days, but Mars takes the length of 687 Earth days to orbit the Sun, Jupiter takes 12 Earth years, and Pluto around 250 Earth years.
A planetary alignment, as seen from Earth, occurs when, by coincidence, a number of planets are in approximately the same position in the sky.
However, even the nearest planet to us - that's Venus - is too far away for it to have any effect on Earth. The only body that does have any real effect on us - apart from the Sun - is the Moon, which simply produces tides in our seas. That's all.
So the bottom line is that there is nothing whatsoever to worry about.
It is a piece of meaningless drivel invented by scam artists ("buy my survival kit and avoid the apocalypse"), kooks and cultists. Nothing is lining up that doesn't do it annually. Why would a line up pick on Earth to destroy when the solar system has seven other planets, half a dozen dwarf planets, 185 moons, and swarms of asteroids?
You are mistaken by this meaning, we and the Illuminati that are staying on our planet are the last resistance not swallowed up by the EOA (Empire of Aliens) and on December 21st the EOA are coming to align the last race in the galaxy under one universal Empire.
A lot has been asked and written about that on this forum -- ad nauseam, in my opinion.
So instead, see if this has enough detail to answer your questions: http://www.2012hoax.org/galactic-alignme…
and come back if you have more specific questions.
The full name is "Galactic Alignment HOAX". get the idea.
