The earth ulis called a blue planet because of the presence of abundance of water in it. About 70 percent of the earth's crust is covered with water. And this imparts it with a blue colour as seen from the space.
Earth is not named after a person, real or mythical. Earth is the only planet not named after a Roman god. It is instead named after what we live on, earth (or soil). IN ADDITION: Uranus is actually named after a Greek god, not a Roman god. (But the name is Roman) The name Earth comes from the Old Saxon word 'ertha', the dutch word 'aerde' and the German word 'erda'. See the related link for more information.
