* The Big Bang: The universe is estimated to be about 13.8 billion years old. This is based on observations of the cosmic microwave background radiation, a faint afterglow of the Big Bang.
* Formation of the Solar System: Our solar system is estimated to be about 4.6 billion years old. This is based on radiometric dating of meteorites and other objects in the solar system.
Therefore, the universe is roughly three times older than our solar system.
