Earth

Earth is the third planet from the Sun and the only astronomical object known to harbor life. It is home to the wasteland and all of it's inhabitants, including the human race, and underwent severe climate change following the Nuclear War of 1993. As of the apocalypse, Earth was believed to have been formed over 4.5 billion years ago, undergoing various extinction events, causing entire forms of life to die out.

Before the apocalypse, Earth had a mainly nitrogen-oxygen atmosphere and was covered in most part by water. However, following the nuclear devastation of the planet, it's stratosphere contains a much higher degree of soot and radioactive particles. Landmass has also shifted both due to the nuclear explosions and by the passing of time.

Climate
In recent years, the Earth has experienced many new natural disasters due to the sudden change of it's climate and composition. Earthquakes are now common in some places where they previously weren't; tidal waves and hurricanes are much more frequent; sandstorms ravage many arid places with incredible frequency; and mysterious radiation storms known as emissions became suddenly common near known exclusion zones.

Orbit
Earth is orbited by one main natural satellite (the Moon) and various old-world satellites; all of which are too small to be seen with the naked eye. Earth itself orbits the Sun, along with seven other planets (Mercury, Venus, Mars, Jupiter, Saturn, Uranus, and Neptune) and various dwarf planets (Ceres and Pluto).
