As a new millennium begins we take a look at how our Earth and Moon came to be. Patrick Moore is joined by Professor Chris Kitchin to discuss how distant planets of other suns, ancient meteorites, and devastating collisions between worlds give us clues as to how the Earth and Moon grew from billions of dust grains, each too small to see.
