Formation of the solar system. Computer illustration showing the stages that formed the solar system. From left to right: The Sun formed from a collapsing nebula some 4.6 billion years ago. The remaining dust and gas formed a rotating disc surrounding the Sun. Slow gravitational attraction (accretion) of small particles formed rocky asteroids (planetesimals),which in turn clumped together to form either the planets,or remained scattered like the present-day asteroid belt. As the planets formed they settled into their current orbits around the Sun | |
