Age of solar system from radiometric dating

But they could not say just how long such processes had taken, and thus how old their fossils were.

Thanks to rocks collected during the Apollo 14 mission, researchers say they’ve finally pinpointed the exact age of the Moon, and it turns out, our lunar neighbour is an incredible 4.51 billion years old.

They are considered to be the building blocks of the inner planets, Mercury, Venus, Earth, and Mars.

Chondrites are aggregates of three major components: refractory Ca-Al-rich inclusions (CAIs), less refractory ferromagnesian silicate spherules called chondrules, and a fine-grained matrix.

The great physicist Lord Kelvin had countered that the planet was actually relatively young — perhaps 20 million years old.

He came up with that figure by estimating how long it had taken for the planet to cool down to its current temperature from its molten infancy.

In class we discussed the formation of the solar system and planets, and the use of radiometric dating techniques to measure dates.

In this problem set, we bring together these two concepts and ask the fundamental question: How old is our solar system?However, despite its importance, the age of the Moon has never been accurately determined," reports the team, led by Melanie Barboni from the University of California, Los Angeles.In case you need a refresher, the Moon is thought to have formed from the leftover matter that was sheared off Earth after a collision with Theia - a planet-sized object that existed in the early Solar System - or perhaps a bunch of smaller objects.Although we’ll talk in more detail about these topics later in the course, for now we can use them to understand solar system formation processes.Of course, fundamentally the age of the solar system is the age of the universe, which present estimates suggest is about 12 billion years.We know that CAIs and chondrules formed at nearly the same time as the Sun (4.56 billion years ago), but we don't know the details of how or where the CAIs and chondrules formed.

    That's where the sexual assault happens." The Cleveland Rape Crisis Center doesn't track this through numbers and because many sexual assaults go un-reported, it's tough to determine the increase seen here.

    The first Spy Kids film was a huge success, and subsequently two sequels, Spy Kids 2: The Island of Lost Dreams and Spy Kids 3-D: Game Over were filmed.
