The Solar System formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The vast majority of the system's mass is in the Sun, with most of the remaining mass contained in Jupiter.
Why is the Earth younger than the moon and meteorites?: Current estimages of the age of the Solar System are 4.5 billion years, but the oldest rocks on the Earth are only 3.6 billion years old. This is younger than the oldest rocks from other solar system objects, why? Earth is geologically active. Earth has a hot, molten interior.
