how to planet create ?? (+20) ENG Plz ~~ urgent....

This answer refers to a Theory about forming of planets.

Step1:Long time ago,there are only rocks,gas and dust in the solar system.

Step2:The rocks started to crash together by gravity and form a larger rock.

Step3:Some of the rocks have a greater mass and its gravity became larger.

Step4:These big rocks gain many small rocks and dust and their gravity became very big.

Step5:Almost all small rocks are attracted to form large rocks,and the large rocks became planets.

Step6:The planets attract gases to form atmosphere.

Step7:some of the planets have unstable orbit(軌道) so they crashed into the sun or into other large planets.
