Is Moon Older Than The Earth?
Many scientists thought that the moon could have been a big piece of earth, broken off from the earth millions of years ago. The other possibility was that the moon was formed along with the earth with the same gas cloud that formed the earth. Another possibility was that the moon was formed somewhere outside the solar system and when came near the earth, started rotating around it because of the earth’s gravity.
When the astronauts landed on the moon and brought back some rocks, scientists found out that the moon is not made out of the same elements as the earth. They were surprised to discover that the moon rocks were more than three and a half billion years old. But some of these rocks were more than four billion years old – older than any earth rocks. The soil on the moon was also of the same age. And there may be more rocks older them even these on the moon.
Because of this scientist now are not sure how the moon was born, or what is its real age. It could be older than the earth!
