The age of Earth was calculated to be about 24-40 million years based on the laws of thermodynamics. Unknown at the time was that the Earth has an internal heat source (radioactive decay) In 1899, John Joly (Irish) calculated the rate of delivery of salt to the ocean.
However, our best estimates place the age of the Solar System at 4.5 to 4.55 billion years. The Sun is about 4.57 billion years old, so is the solar system.The age of the Solar System is determined through the radiometric dating of heavy elements such as uranium. Measurement of radioactive decay rates allow us to determine when the elements in the Solar System were formed.
