 What If Earth got Kicked Out of the Solar System?

Why would our lovely earth come out of the solar system, without any meaning??

There is one reason for this: another star that may pass by our earth. The gravitational pull of that start may dislocate our earth with no orbit, starting to float in these large, dark, empty galaxy for millions of years. Until we don't find another suitable planetary system for our human settlement!!

Let's go a little back. In a way of story!!

A day before a shinning mass crossed over the earth, all the peoples are mesmerized by seeing it, but knowing the truth it was the start of a new era, A NEW HUMAN ERA, where people lives isolated from the outside world for most of the times for the extreme coldness. Now the earth is no longer a part of our loving solar system rather it is floating in outer space for decades. NO TREES, NO ANIMALS, NOTHING LEFT all died due to coldness only humans were survived by the power of their technology. 

We, humans, live on closed buildings, and with the help of geothermal energy obtained beneath the earth's surface from its core.

Foods are grown inside specialized cabins that have artificial sunlight and soil. 

The only hope is another planet to again lead a normal life like on earth before.
