The age of Earth is estimated to be 4.54 ± 0.05 billion years (4.54 × 10 9 years ± 1%). This age may represent the age of Earth's accretion, or core formation, or of the material from which Earth formed.
19 de oct. de 2023 · Scientists have calculated the age of our planet to be approximately 4.5 billion years. But how did scientists determine that age? The answer is complicated: It involves everything from observation to complicated mathematics to understanding the elements that make up our planet.
Los geólogos y geofísicos modernos consideran que la edad de la Tierra es de unos 4540 millones de años ± 1 %. Esta edad había sido determinada mediante técnicas de datación radiométrica de material proveniente de meteoritos y es consistente con la edad de las muestras más antiguas de material de la Tierra y de la Luna.

Based on the very old zircon rock from Australia we know that the Earth is at least 4.374 billion years old. But it could certainly be older.
Earth is estimated to be 4.54 billion years old, plus or minus about 50 million years. Scientists have scoured the Earth searching for the oldest rocks to radiometrically date. In northwestern Canada, they discovered rocks about 4.03 billion years old.
In numerical terms, the best estimate of Earth’s age so far is that it is close to 4.6 billion years old. But what does that mean exactly? If one uses a human lifetime of 75 years as a measure, the time between Earth’s formation and today has taken more than 61 million human lifetimes!
