Early solar system. Artwork of the early solar system during its formation. The Sun (orange,centre) 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 these rocky asteroids (planetesimals). They in turn clumped together to form Earth-like rocky planets,or remained scattered like the present-day asteroid belt | |
