Our home planet is the third planet from the Sun, and the only place we know of so far that’s inhabited by living things.
While Earth is only the fifth largest planet in the solar system, it is the only world in our solar system with liquid water on the surface. Just slightly larger than nearby Venus, Earth is the biggest of the four planets closest to the Sun, all of which are made of rock and metal.
Earth is the only planet in the Solar System whose English name does not come from Greek or Roman mythology. The name was taken from Old English and Germanic. It simply means "the ground." There are, of course, many names for our planet in the thousands of languages spoken by the people of the third planet from the Sun.Ten Things to Know About Earth
Storytellers explore the nature of our planet and possible alternate realities in many books, movies, and television shows. The iconic film "Planet of the Apes" (and its sequels) takes place in a future in which astronauts "discover" a planet inhabited by highly intelligent apes and primitive humans, only to realize later, much to their dismay, that – spoiler alert! – it was Earth all along.
In the long-running and re-booted television series "Battlestar Galactica" – tired survivors of a war with highly evolved robots called Cylons are on a quest to find Earth, a long-lost colony.
In other stories, Earth has been abandoned or destroyed, such as in the Joss Whedon series "Firefly," or the book and its film adaptation "The Hitchhiker's Guide to the Galaxy." In the animated feature "Titan A.E." – Earth has been destroyed by an alien species, but a well-placed planet builder recreates it and all the species that live on it.Kid-Friendly Earth Read More
