  Hey! Around 4.5 billion years!
  The earth is around the same!

  The moon is pretty old – it was formed around 4.5 billion years ago! The most widely accepted theory for how it was formed is that a rocky body collided with the Earth and the debris from this crash came together orbiting around the Earth to make the Moon!

  Very old! About the same as the Earth – about 4.5 billion years.

  As the others have said, the most accepted theory for it’s formation was because of a giant collision with another very large rocky body. We know how this because we have analysed rocks collected during the Apollo moon landing missions in the 1960’s and the rocks they collected have very similar composition and age to those found on Earth.

  It looks like you have already got some great answers to your question so I thought I’d tell you another cool fact about the Moon. Did you know there are also big mountains on the Moon like there are on Earth?😵

  Scientists in Germany actually measured how old the moon was by taking measurements of moon rocks. They found that moon is 4.53 billion years old! That is very old! Imagine all the things that have happened in that time.
