The Earth And Solar System Age

The inner solar system also contains near earth asteroids many of which cross the orbits of the inner planets. This dating is based on evidence from radiometric age dating of meteorite material and is consistent with the radiometric ages of the oldest known terrestrial and lunar samples.

Our cosmic year begins with the formation of the universe at midnight.

The earth and solar system age. The age of the solar system derived from the study of meteorites thought to be the oldest accessible material around is near 5 billion years. The oldest such meteorites we have found suggest the age of their formation and thus the age of the solar system to be 4568 billion years. Scientists think that the earth is 454 billion years old.

Coincidentally this is the same age as the rest of the planets in the solar system as well as the sun. The oldest meteorites ever dated in the solar system are 456 billion years old the oldest minerals on earth are 44 billion years old and the oldest rocks on earth are 4 billion years old. Following the development of radiometric age dating in the early 20th century measurements of lead in uranium rich minerals.

The age of the earth is estimated to be 454 005 billion years. By studying several things mostly meteorites and using radioactive dating techniques specifically looking at. How old is the solar system.

How old is the earth. This age may represent the age of the earths accretion of core formation or of the material from which the earth formed. To appreciate its depth well map the history of the universe into one of our twelve month calendar years.

For comparison the milky way galaxy that contains the solar system is approximately 132 billion years old. The outer region of the solar system is home to the giant planets and their large moons. The centaurs and many short period comets also orbit in this region.

Some of them are potentially hazardous objects. This is a very long time. These ages are very consistent because the meteorites had to form before the accretion of our planet and the earth had to cool down before the first minerals could crystallise.

The age for the earth and the rest of the solar system is about 455 billion years plus or minus about 1. The oldest rocks on earth are dated as 38 billion years. That is a question that cuts to the heart of it all.

Intermediate the oldest rocks on earth have been destroyed by plate tectonics so to get the age of the solar system we turn to meteorites instead. That of the earth is taken as 46 billion years. By using not only the rocks on earth but also information gathered about the system that surrounds it scientists have been able to place the age of the earth at approximately 454 billion years.

The universe is between 10 and 20 billion years old and the common accepted age is 15 billion years.
