The Moon, which seems so old, is actually much smaller than we thought

  • According to new research, the moon is 85 million years younger than scientists once thought.

  • Computer simulations showed that the Moon was formed about 4.425 billion years ago.

  • How and when the moon was formed is a matter of controversy among planetary scientists for a long time.

The moon, it turns out, is much lower than previously thought scientists.

Researchers at the German Aerospace Center and the University of Munster have released new estimates for the age of the moon. According to their modeling, it is 85 million years younger than current estimates.

Scientists have long speculated that the Moon formed about 4.51 billion years ago when a Mars-shaped object (which we dubbed Thea) collapsed into Earth. At that time, the courage of our newly formed planet was taking shape.

The collision ripped Earth’s earthworm and caused it to orbit, where it collided with a huge ring of dust and rock that collided with each other. “This led to the creation of the moon in a short time, in a few thousand years,” planetary scientist and researcher Koothor Doris Breuer of the German Aerospace Center said in a statement.

Breuer and his colleagues revealed in their paper published in the magazine Science advance, That this infamous effect took place 4.425 billion years ago, about 25 million years or so. After the impact, the moon looked like Mustafar – a molten marble piping hot magma ocean that is more than 600 miles deep.

Scientists used computer simulations to show how long it would have taken for the moon’s magma ocean to freeze, as it would help determine the exact age of the moon. His model indicated that it took 150 to 200 million years to make that magma completely crystalline. Previous models have suggested that it took only 35 million years for the moon’s hard, rocky outer structure.

The impact also kickstarted the formation of the Earth’s core. Heavy elements such as nickel and iron drowned towards the center of the planet, while a layer of silicate rock formed the mantle layer around it.

This is the first time that the age of the Moon can be directly linked to the event occurring at the end of Earth’s formation, said the formation of the core, said Thorsten Klein, planetary scientist at the University of Munster in Germany. The statement said.

Over the years, we have been able to shine information and fragments from the rocks of the moon brought back during the Apollo missions and the Luna missions to Russia. It has been more than 50 years since we first set foot on the lunar surface, and we still have a lot to learn.
