The Moon was formed about 95 million years after the birth of our Solar System, in a collision that also settled the structure of Earth as we know it, according to the latest attempt at dating that impact.
A study in the journal Nature said the crash between an early, proto-Earth and a Mars-sized object that dislodged what would become the Moon, happened some 4.470 billion years ago -- give or take 32 million years.
Apart from creating our satellite, the event is also believed to have marked the final phase of Earth's core formation from molten metals sinking to the centre from a superhot surface.
Previous estimates had ranged from an "early" impact about 30 million years after the start of the Solar System, to a later one as much as 200 million years after.
The Solar System itself is known to be 4.567 billion years old thanks to accurate dating of some components of meteorites -- the oldest materials to be found on our planet.
Earth is believed to have formed at some time during the first 150 million years.
Many earlier age estimates had been based on measuring the rate of radioactive decay of atomic nuclei found in rocks.
For the new study published in the journal Nature, a team of planetary scientists from France, Germany and the United States created a computer model of how dust and rock accumulated in the early Solar System to form tiny planets called planetesimals.
These grew into "planetary embryos" that ended up as the rocky planets we know today -- Mercury, Venus, Earth and Mars -- through a succession of giant impacts, according to the new model.
Each massive collision allowed the planets to "accrete" or accumulate matter. In Earth's case, the lunar impact would have marked its final major growth event.
The team also looked at the chemical composition of the Earth's mantle to trace the amount of material the planet accumulated after the impact -- only about 0.5 percent of its total mass.
If the impact had happened early in the Solar System's history, there would still have been many free-floating planetesimals for the Earth to sweep up, and if it was later, fewer.
The evidence suggested Earth took 95 million years to form, "which confirms it as the planet in our Solar System that took the longest to form," study co-author Alessandro Morbidelli told AFP by email.

“.. Nuclear Power Revealed
So let me tell you what else they did. They just showed you what's wrong with nuclear power. "Safe to the maximum," they said. "Our devices are strong and cannot fail." But they did. They are no match for Gaia.
It seems that for more than 20 years, every single time we sit in the chair and speak of electric power, we tell you that hundreds of thousands of tons of push/pull energy on a regular schedule is available to you. It is moon-driven, forever. It can make all of the electricity for all of the cities on your planet, no matter how much you use. There's no environmental impact at all. Use the power of the tides, the oceans, the waves in clever ways. Use them in a bigger way than any designer has ever put together yet, to power your cities. The largest cities on your planet are on the coasts, and that's where the power source is. Hydro is the answer. It's not dangerous. You've ignored it because it seems harder to engineer and it's not in a controlled environment. Yet, you've chosen to build one of the most complex and dangerous steam engines on Earth - nuclear power.
We also have indicated that all you have to do is dig down deep enough and the planet will give you heat. It's right below the surface, not too far away all the time. You'll have a Gaia steam engine that way, too. There's no danger at all and you don't have to dig that far. All you have to do is heat fluid, and there are some fluids that boil far faster than water. So we say it again and again. Maybe this will show you what's wrong with what you've been doing, and this will turn the attitudes of your science to create something so beautiful and so powerful for your grandchildren. Why do you think you were given the moon? Now you know.
This benevolent Universe gave you an astral body that allows the waters in your ocean to push and pull and push on the most regular schedule of anything you know of. Yet there you sit enjoying just looking at it instead of using it. It could be enormous, free energy forever, ready to be converted when you design the methods of capturing it. It's time.
So in closing, do you understand what you're seeing? You're seeing intelligent design, quantum energy and high consciousness. You are seeing changes in Human nature. You're seeing countries putting things together instead of separating. You are seeing those who don't want war and instead want peace, good schools for their children, safety in their streets and a say in their government. We told you it was going to happen this way. I want my partner to teach these things that I have said in his 3D lectures for awhile. Many won't be able to know these things otherwise. …”
