The Moon Is Much Older <br />Than Previously Believed A new report that observed the moon's rocks says the astronomical body formed 50 million years after <br />the solar system's creation. That is 100 million years older <br />than previous reports, making <br />the moon 4.51 billion years old. Samples of the moon were studied at <br />the Institute of Geology and Mineralogy. It is believed the moon was created after <br />the Earth was struck by a huge space formation. Pieces of the Earth then drifted off into space <br />and formed our closest neighbor in orbit. Large amounts of magma are believed to have existed <br />on the moon's surface before it cooled <br />and became what it is today. Thanks to a long period of inactiveness, <br />chemical samples of the moon can deliver <br />a clearer picture into how it came to be. Study co-author Peter Sprung, via 'The Independent'
