Earth

Earth, also known as Comic Earth, Terra and Turra, was one of the four major planets in the Solar System.

Formation
The precise age of Earth is unknown, but is widely accepted that it was formed a short time before the Origin, in year 0.

It has been theorised that Earth could have been created from the space clouds that created the Pre-origin planets. This is due to a similar geological makeup in the crust of these planets.
