Earth, (also known as Gaia, Sol Prime, Sol III or Terra) is the third planet in the Sol System and the homeworld of Humanity. It is also the first natural known Me-Class world to humanity. Earth has one natural satellite, the Moon.
As of 200000, the Earth has been through countless events and has it many experiments conducted on her. Earth is currently a paradisiacal housing planet, one of the top tourist destinations in the Milky Way, and busy trading hub. Many green megacities can be seen from orbit. Some megacities even reside in the vast oceans.
Most farming on Earth is accomplished by massive farming towers built in places where conditions were hostile in the past. These farms comprise of up to 32% of the food income on Earth. About 6% of the crops come from large floating farms on the oceans, which are powered hydroponically. The remaining 62% of the food comes from imports.
The Earth is much greener than it was back in the earlier ages thanks to the population crash and subsequent ruralization of most of the large cities. Each building, home, and megacity is now required to have small plants and/or grass growing on their roofs as well as in their lawns. There were even a few cities that were closed off and abandoned.
Most of the energy on Earth comes from clean renewable energy sources such as solar and wind as well as newer forms of nuclear fusion that are clean and safe for the environment. A tiny fraction of the energy is from geothermal processes in the Earth's mantle and outer core, while the rest come from buildings themselves.
Being the homeworld of Humanity, the global population is around 15 billion currently, excluding the inhabitants of orbital habitats and space cities. Most of the population resides in the dense megacities, while the rest live in parts of reclaimed nature, mostly farming for fun.
Earth is the most diverse world culturally, as it contains thousands of regions, some of which still follow fragmented state borders.
Earth has one of the most diverse climates in the entire system. Temperatures range from being cold enough at the poles to freeze water and warm enough at the equator to fry an egg on a metallic surface. Each region of Earth has a unique biosphere able to support a variety of plant and animal life.
In celebration of Vega becoming Earth's new North Star, a petition went through the terrestrial governments, pleading for a beautification type project, as everyone was obsessed with physical beauty at that time as well as making Earth look more appealing. Many asteroids and comets were diverted and were eventually crashed into each other in controlled collisions. A few smaller asteroids were placed in orbit in order to keep the rings from degrading, and trillions of nanites were released to construct the rings.
As well as breaking apart the asteroids and comets, the nanites were responsible for giving the color of the rings. The nanites then rained down after completing their tasks, forming the most brilliant meteor shower seen on Earth in millennia. The ring system has since remained stable.
After the War of the Decamillenial Transition and the Split of the Confederacy, Earth was left with only one billion inhabitants, mostly the richer who used automation to live and survive. The descendants of those evacuated began to slowly come back, although the majority had made new worlds for themselves, most notably three copies of Earth using Terrashaping. By the year 21000, Earth's megacities had been repopulated. By the year 25000, the population remained steady at around 30 billion, mostly within the megacities once again, although the land was allowed time to fallow and regrow.
