The planet we human beings live on is called Earth.
Earth is the third planet from the sun and the fifth largest.
The name comes from Old English and Germanic. All the way back to the sixteenth century, was the first time that it was of a space craft. In the twentieth century we were able to take pictures of the planet from outer space. These pictures are very helpful because we can make accurate predictions in weather reports. The Earth is divided into several layers which have distinct chemical and seismic properties.
