The Solar System is about 4.6 billion years old. This age is estimated based on the formation of the Sun and the surrounding protoplanetary disk from a collapsing molecular cloud, which occurred roughly 4.6 billion years ago

. Radiometric dating of the oldest meteorites, which are remnants from the early Solar System, supports this estimate, with ages around 4.57 billion years

. More precise recent measurements place the Solar System's age at approximately 4.5684 billion years, slightly older than previous estimates by about 1.1 million years

. In summary, the consensus age of the Solar System is about 4.568 billion years, derived from dating the oldest solid materials formed during its birth.
