Based on the radiometric dating of meteorites, it is widely accepted by scientists that Earth is approximately 4.6 billion years old.12

This age is determined by analyzing the isotopic composition of meteorites, which are considered to have formed at the same time as the rest of the solar system from a primeval cloud of gas and dust. By studying the growth curve of terrestrial lead isotopes and extrapolating back in time, researchers find that the results coincide with the ages measured in meteorites, confirming that Earth and these bodies share a similar history of formation. While some models incorporating the decay of hafnium-182 to tungsten-182 suggest that the accretion process concluding Earth's formation may have taken about 100 million years—placing the planet's age at approximately 4.5 billion years—the 4.6 billion-year figure remains the standard estimate for the age of the solar system's development.1
