Why doesnt it circle it with its one circle like and atom, they wont colide each other because the distance is varied from each other, and what is the force that made them go circling the sun in a line ? if the argument is about the gravity pulling each other then it would even happen now, what force did make the planets line up ?

Our solar system formed from a huge molecular cloud in space (a nebula). This cloud began to contract under its own gravity, and it's natural for something collapsing in this way to begin rotating. As it contracted, the rotation sped up due to conservation of angular momentum, the same way a figure skater spins faster as she pulls in her arms. The rotation causes the cloud to flatten into a disk, and lumps of gas, dust and debris in the disk continued to attract more matter, forming the planets. Since the planets formed from a disk, their orbits are more or less in line with each other.

The sun started of as a cloud of gas. This gas started collapsing under its gravity and started spinning - spinning in the direction all the planets spin today. This also flattened the cloud out

As it collapsed further, the center became hot nuclear fusion started and our sun was born. The gas and dust that was orbiting then started clumping together to form small rocks, then larger asteroids and finally, the large bits of rock attracted even more and eventually the planets were formed - still spinning the same direction.

This was how the planets were lined up, the planets that crashed did crash - thats how our moon was formed. Around 4 billion years ago a planet the size of mars hit the Earth which caused enough debris flung up to space to form the moon.

The planets are trying to travel in a straight line from the energy they got in the big bang and the rotation from when the star was being born. The suns gravity affects this straight line movement and attracts it towards the sun so the straight line becomes a circle - the force of gravity from the sun and the kinetic force of the planets balanced.

It is believed that the sun and the planets evolved from a huge,swirling cloud of gas and dust that condensed over a time span of hundreds of millions of years.This gas cloud was very likely in the shape of a disk and when the planets came to be within this cloud,they all formed basically along the same plane.Thus the revolution (as well as the rotation)of the planets must have originated at the time they formed from a revolving disk of hot gases.So they are revolving in the same plane.

through fact the universe is Flat, for choose of a greater appropriate rationalization, the place the action of Stars, Galaxies and Planets all persist with the comparable line of tension alongside what's termed the Ecliptic airplane. this is the reason of what many have self belief will happen in 2012, while our photograph voltaic device aligns with the centre of our Galaxy. i'm hoping this is smart.
