how do scientists determine the age of the solar system?
How Old is the Solar System? How old is the Solar System? That is a question that cuts to the heart of it all. By studying several things, mostly meteorites, and using radioactive dating techniques, specifically looking at daughter isotopes, scientists have determined that the Solar System is 4.6 billion years old.
Confidence votes 8.3K. 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. The most current data places the age of these elements at 4.567 billion years old.
