Earth is the third planet from the Sun and the densest and fifth-largest of the eight planets in the Solar System.
It is also the largest of the Solar System's four terrestrial planets.
It is sometimes referred to as the World,the Blue Planet.
Home to millions of species including humans,Earth is currently the only astronomical body where life is known to exist.
The planet formed 4.54 billion years ago,and life appeared on its surface within a billion years.
About 71% of the surface is covered with salt water oceans,the remainder consisting of continents and islands which together have many lakes and other sources of water contributing to the hydrosphere.
Liquid water,necessary for all known life,is not known to exist in equilibrium on any other planet's surface.
Both the mineral resources of the planet,as well as the products of the biosphere,contribute resources that are used to support a global human population.
These inhabitants are grouped into about 200 independent sovereign states,which interact through diplomacy,travel,trade,and military action.
What a f***king whole universe.
