what is theory behind planets orbital formation in our solar system?

Question

is there any one can explain me in detail about orbits of our
planet ,how are they formed? or give me some web address

Answer 1

The planets in our Solar System formed about 4.5 billions years ago through the collisions of smaller bodies called planetesimals. The oribts of the planets are a consequence of the parameters of those collisions. The planetesimals coalesce out of the young star's accretion disk, a giant, flat cloud of dust. As planetesimals grow, their rate of growth increases because they have more surface area for smaller particles to stick to. Eventually, the planetesimals are large enough to have significant gravitational effects on each other. After that point, similarly sized planetesimals that collide usually smash apart, but large ones may be able to absorb the energy of an impact with a small one, adding to its mass. After a certain point, all of the planetesimals are ejected into remote orbits or captured as satellites as a result of the gravity of the planets, and only the planets planets remain.

The central star has an affect the size of planets at different distances, because of its effect on the original planetesimals. The heat of the nascent star keeps certain substances in energetic phases, preventing them from becoming part of forming planetesimals. This is why the planets closest to the Sun are small and rocky. Also, when the star finally starts thermonuclear fusion, its solar wind blows away the remaining gas and dust, and the planets finally stop growing.

centrifical force pulls it to the center equator of the sun
