How was the solar system formed ks3?
The Solar System was formed around 4.6 billion years ago from a large cloud of dust and gas, called a nebula . This collapsed under its own gravity, transferring gravitational potential energy to kinetic energy in its particles. As the nebula collapsed it became denser, and rotated more rapidly.
Why is Pluto not a planet ks3?
Pluto is not a planet because a planet must: orbit the Sun; have sufficient mass to be round; not be a moon of another object; have removed small objects from the area around its orbit. In 2006 the IAS declared that Pluto had not cleared the area around its orbit, so it was reclassified as a dwarf planet.

How did the solar system form ks2?
The solar system was formed about 4.7 billion years ago. It probably started as a loose cloud of gas and dust. Scientists think that a force called gravity pulled parts of the cloud together into clumps. The Sun’s strong gravity eventually pulled the planets into their orbits.
What are asteroids ks3?
Asteroids are comprised of rock and metal, and are smaller than planets. Most of them are found in an ‘asteroid belt’, in orbit around the Sun between Mars and Jupiter. The orbits of some asteroids cross the Earth’s orbit.
