Jupiter is the fifth planet from the Sun in the Solar System. Is the biggest planet.
In late 2009, all of the planets started to align themselves, with Jupiter doing the same, as a massive solar flare erupted from the Sun. The combination of the planetery alignment and the solar flare caused a cataclysmic event to occur on Earth, which caused the crust to becoming unstable and letting the planet come to an end in 2012.
When the 2012 apocalypse ended, Jupiter continued to remain in its orbit as time was reset to year one, with the now uninhabitable Earth displaying a new changed landscape.
