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.
Discover how scientists estimate the age of Earth and what clues they use to unravel its ancient history.
Oct 19, 2023 · This makes finding an exact age for Earth difficult, because the original rocks that formed on the planet at the earliest stages of its creation are no longer here. The oldest rocks that have been found are about 3.8-billion years old, though some tiny minerals have been dated at 4.2 billion years.
Jun 3, 2021 · The best scientific research to date suggests that our planet formed about 4.54 billion years ago. That’s 4,540,000,000 years!
Its age is put at 4.55 billion years – 500 million years earlier than its oldest surviving rocks – on the three-fold assumption that (i) it must be the same age as meteorites, (ii) meteorites are the remains of a cloud of dust and gas from which the whole solar system was born, and (iii) the rate of radioactive decay has always been the same.
