The oldest rocks on Earth found to date are the Acasta Gneisses in northwestern Canada near the Great Slave Lake, which are 4.03 billion years old.

Rocks older than 3.5 billion years can be found on all continents.

Research groups in Australia found the oldest mineral grains on Earth.

These tiny zirconium silicate crystals have ages that reach 4.3 billion years, making them the oldest materials found on Earth so far. The rocks and zircons set a lower limit on the age of Earth of 4.3 billion years, because the planet itself must be older than anything that lies on its surface.

Several attempts to scientifically date the planet have occurred over the past 400 years.

Scientists attempted to predict the age based on changing sea levels, the time it took for Earth or the sun to cool to present temperatures, and the salinity of the ocean.Samples returned from the Apollo and Luna missions revealed ages between 4.4 and 4.5 billion years, helping to constrain the age of Earth.In addition to the large bodies of the solar system, scientists have also studied smaller rocky visitors to that fell to Earth. Some are cast off from other planets after violent collisions, while others are leftover chunks from the early solar system that never grew large enough to form a cohesive body.Gravitational interactions coalesced this material into the planets and moons at roughly the same time.By studying other bodies in the solar system, scientists are able to find out more about the early history of the planet.Since the planet Earth doesn't have a birth certificate to record its formation, scientists have spent hundreds of years struggling to determine the age of the planet.
