The Earth (Q2 on Wikidata) is located in the Solar System and is our native home
planet. One of the reasons why there is life on this planet is thanks to
the Sun giving us the light we need, the large amount of water (which
covers about 71% of the planet's surface). Scientists think life on
Earth began about 4 billion years ago.
Earth is the third planet from the Sun and the fifth largest in the Solar System, it has an ellipsoid shape. It has formed from space dust nearly 4.5 billion years ago during the formation of our Solar System. Soon after its formation it was struck by a Mars-sized body, called Theia, which led to the formation of the Moon, Earth's only natural satellite.
The 1911 Encyclopædia Britannica talks about Earth:
The terrestrial globe is a member of the Solar system, the third in distance from the Sun, and the largest within the orbit of Jupiter.
[...]
In its earliest history the mass now consolidated as the Earth and Moon was part of a vast nebulous aggregate, which in the course of time formed a central nucleus-our Sun-which shed its outer layers in such a manner as to form the solar system[.] The moon may have been formed from the Earth in a similar manner, but the theory of tidal friction suggests the elongation of the Earth along an equatorial axis to form a pear-shaped figure, and that in the course of time the protuberance shot off to form the Moon[.] The age of the Earth has been investigated from several directions, as have also associated questions related to climatic changes, internal temperature, orientation of the land and water (permanence of oceans and continents)[.]
One unique thing about our Earth is that it is deeply, deeply lonely. As far as we are aware, no other planet can sustain life, and so we as Earthlings are alone, so we make art, we sing songs, fall in love, hunt and kill, start wars, and destroy empires.
