Earth (planet)

Earth, (also the world or Gaia) was the third planet from the Sun, the densest planet in the Solar System, the largest of the Solar System's four terrestrial planets, and the only astronomical object known to sustain life. It was the home of the Blockheads civilization.

Earth's evacuation
At the beginning of 2200, scientists discovered that the Sun was getting weaker. In the next four years, the Sun's activity dropped completely dead. Temperatures began to cool off on Earth and satellites were searching among the stars for a new Earth planet. In 2214, planet HDJ200-B or also known as Terra, was discovered in another galaxy. From 2214 till 2218 a massive evacuation arc was build for thousands of Blockheads. Blockheads were frozen into space coffins to wake up later when the arc reached the new planet. After escaping the Solar System, the Sun finally imploded or collapsed.
