Planet X

Earth has a deadline. In forty-five days, a rogue planet called Planet X is due to pass near Earth. Scientists have discovered that every 4600 years, Planet X returns on its elliptical, comet-like orbit around the sun. As Planet X passes near Earth, it will create a disastrous event of Biblical proportions, the end of the world as we know it. Due to Planet X's mass, magnetism, and density, it will disrupt the surface of every planet it encounters, and as it nears Earth, it will create a massive polar shift.
Every known volcano, both active and dormant, will erupt, creating devastating planetary earthquakes. Seventy-five percent of Earth's population will die initially. Another twenty percent will starve to death as volcanic ash covers the Earth and blocks out sunlight for the next nine months. The few million people who are still alive will only survive by eating the sick, weak, and dying's flesh. Unless something is done, in forty-five days, most of the human race will vanish from the face of the Earth.
