Dear MEL Topic Readers,
The moon is
about 85 million years younger than we thought, new study finds
Do you have
any idea how and when the moon was formed? According to a widely supported
hypothesis, about 4.5 billion years ago, an ancient planet in the early Solar System collided with the early Earth when it was still heating up and changing
rapidly. The collision created a lot of debris that orbited around Earth and
later formed the early Moon. So, it has been widely assumed that the Moon was
born about the same time as the Earth.
Now, a new
study estimates that the Moon was formed about 85 million years after the Earth
when the planet was almost formed solid. Also, it found that it took about 200
million years for the Moon to cool down and became solid from its molten form.
How did the
scientists figure out these super ancient astronomical timelines?
Enjoy reading
the article and learn about the birth of our planet and the Moon.
