Why do the planets go arounds the sun in the same direction, and why do all the planets lie in a flat plane?

Answer 1

Both questions have the same answer: because the hot, dense gas that was the Solar System in earlier times had angular momentum.

In other words, the gaseous material was spinning about an axis, which flattens the plane (think of a baker spinning a pizza). Also, all materials in the system will revolve in the same direction about a central axis, which happens to lie close to the Sun since most of the original matter ended up as a central star.

Answer 2

the planets do not all lie on a flat plane. i think it is pluto that is the farthest from it. its just that maps of the planets often make them seem on a flat plane to better compare them. However, as to why they all revolve in the same direction, it is because the all pulled each other when they were small specs of dust, and then the momentum all went that way when they grew. its a chain reaction!

Answer 3

The best theory, based on the orientation of the planets, observations of orbital behavior and compuational models says t hat the solar system began as a spinning mass of dust and rock. Matter like that will aline into a flat disk. Then local areas of higher than average material started to pull other material towards it by gravitational attactions. this resulted in balls of material which formed into planets.

Answer 4

Actually, they are slightly off the flat plane. This is expected from a system of objects that formed from accretion of a smaller particles as was formed when the sun (so the theory goes) was side-swiped by another star. The plane is formed due to gravity and rotation.

Answer 5

because all matter in our solar system was part of an unorganized cloud. it started spinning, matter clumped together, and the sun and planets were born. obviously, this a very simplistic explanation, but i'm not an astronomer or anything

Answer 6

beforehand the image voltaic equipment replaced into shaped, it replaced right into a swirling disc of dirt and gasses, left over from preturberances probable from some form of supernova experience. As this disc cooled, clumps began to form by using gravitational forces. by using fact the clumps grew larger, so did each and every clump's gravity, consequently pulling further and further dirt and gas in to each clump. those clumps over 1000's of hundreds of thousands of years grew to alter into planets, and each moved around the sunlight in the comparable direction by using fact the preliminary swirling gas/dirt disc. and each planet exists in the comparable plane as that disc besides.

Answer 7

Either the spinning cloud THEORY that people above claim

OR

God made it that way "In the beginning...."
