Our universe includes planets, moons, stars and galaxies and is thought to have been created approximately 13.7 billion years ago.
We live in the galaxy known as the Milky Way, which can be seen from Earth on clear, starry nights. There are billions of solar systems in our galaxy and one of them is our very own solar system. This has eight planets, with our planet, Earth, the third in the row. As far as we know, the Earth is the only known planet on which life is found.
