How did the terrestrial planets form
WebPlanets form from particles in a disk of gas and dust, colliding and sticking together as they orbit the star. The planets nearest to the star tend to be rockier because the star’s … WebWithin the solar nebula, scientists believe that dust and ice particles embedded in the gas moved, occasionally colliding and clumping together. Through this process, called "accretion," these microscopic particles formed larger bodies that eventually became planetesimals with sizes up to a few kilometers across.

WebAs far as our understanding of planetary formation goes, rocky planets tended to form closer to the Sun because the materials they're made of -- silicates and heavier gases -- 'fall' inwards towards the Sun. WebWe know that the Sun sits at the centre of the Solar System with the planets in orbit around it, but these throws up five major problems: The Sun spins slowly, and only has 1 percent of the angular momentum of the Solar System - but 99.9 percent of its mass. Why is this? Terrestrial planets have solid cores - how did they form?
