are all the planet in solar system the same plane in the space or not ? if yes is there any especial reason ? and if no how do they orbits then ? as far as i know they are in the same plane , but is that mean they are exactly in same plane or its some thing near that ? I would also like to know if they all orbit in the same direction ? Is any of the picture below describing them true ?!
