Book excerpt: Looking up at the sky on a clear night, you might see shining stars, a bright moon and mysterious coloured dots but there many more secrets hiding out in space. The Solar System takes readers on a journey from the Earth's surface, through the atmosphere and out into space as you travel from centre of the universe to discover the stars, planets, moons and comets that call our solar system home.
