Tales of the Universe
The Earth, together with 8 other planets: Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto, revolve around a star, our Sun, forming what we call our Solar System. Stars and planets are very different: a star is burning and gives out its own light while a planet just reflects the light from its nearby star.
Our Solar System is in its turn part of a much bigger structure: our Milky Way Galaxy. Our Galaxy consists of huge curly arms coming out of a central region, and we lie in one of these arms. Apart from the Solar System, our Galaxy contains billions of stars, dust, planets, and pieces of rock.
