How old is our solar system? About 4.6 billion years ago, a giant cloud of dust and gas known as the Solar Nebula collapsed in on itself and began to form what would eventually become the Sun and planets of the Solar System. Meteorites, or pieces of space rock that fell to Earth, have helped scientists determine the age of the solar system. Some of these small pieces broke off from moons or planets, and they can provide interesting scientific information about the chemistry and history of their parent body.
