The Earth and the moon have a vital connection. Without it, our planet would be unrecognisable. But what does the moon do for us? Through an immersive combination of real footage and photo real 2D and 3D CGI, this documentary reveals how different our world might be if the moon wasn't exactly where it is now. By examining the unique bond shared by the moon and the Earth we can discover how our own planet was sculpted, how life here evolved and how a rock orbiting a quarter of a million miles away holds the power to shape our future. A BBC Production.
