Earth: Sol III

Summary
Earth, also known as Sol III, is a Temperate Marine Terra in the Sol System and the homeworld of the Federated Planets of Earth. Its atmosphere is comprised of 70.08% N2 and 20.95% O2 making it breathable for Humans and most carbon-based life forms. Life on Earth is predicted to have originated approximately 4.1 billion years ago and has since expanded into one of the most biodiverse planetary ecosystems in the Orion Arm.

As a result of centuries of human habitation, much of the planet's ecosystem has been directly affected, some to greater extents than others. After the 21st century, large swathes of land were lost to the ocean and global temperatures rose by an average of 2°C, causing a reduction in biodiversity and an increase in pollution. As of 2200, 12.3 billion people live on Earth under the flag of the Federated Planets of Earth, the interstellar government formed from the remnants of former nation-states on the planet.

Earth orbits Sol at a distance of 1 AU and has one natural satellite known as Luna or The Moon.
