MOON YOUNGER BY 200M YRS | Moon Is Younger Than our Thought

    The latest issue about Nature says, the moon is billion years old, up to million years younger than thought.  The estimate comes from a new dating of isotopes of lead and neodymium found in samples of ferroan anorthosite,  a crustal rock that derives from magma.  Moons age is more than 200 Million Years.  A common theory for the origin of the moon is that it was created by an impact between a large planet-sized object and the nascent earth. The molten material, or magma, that was ejected from this giant collision progressively cooled, hardening into earth's rocky, barren and airless satellite.  This extraordinarily young age of this lunar sample means that the moon solidified significantly later than previous estimates.
