In 1971, Apollo 14 brought back the 20-pound rock Big Bertha; in 2019, scientists found a fragment that likely came from Earth, excavated about 4 billion years ago

A lunar rock collected by Apollo 14 astronauts may contain a fragment of Earth. This tiny piece of rock is approximately four billion years old. Scientists suggest an asteroid impact blasted it from Earth into space. The Moon was much closer to Earth during that ancient period. This discovery offers a rare glimpse into our planet's early history.
