why do our planets move around the sun on the same plane?

Question

what i mean is all the diagrams of our solar system shows the planets somewhat inline/left and right,why not up and down or all around? if our world is made up of atoms,and the diagrams of an atom shows the particals incircling the nuetron from all around, why not our planets?

Answer 1

The planets formed from a planetary nebula which was dust and gas rotating around the sun. Because it rotated in one direction and in one plane, the planets do the same.

At first, the dust and gas may have been a little more erratic, but over time, anything that was far out of the orbital plane would have a much greater chance of colliding with something else and bringing it back into line with all the rest.

Answer 2

Our planets were formed from a solar extrusion caused by a massive passing star billions of years ago. The passing system also lost three of its most distant trubutaries (acquired by our sun), which had different orbits from the planets produced by the extrusion. This accounts for the 'retrograde' motions detected by astronomers. This happened when our sun was still pulsing similar to stars we see called Cepheid variables. I could write a little more on this, not much more, but I will stop here because I am sleepy and there are a lot of smart people out there waiting to jump on mistakes. However, what I have said is for SURE. Also, we still have much to learn about our own solar system, including exactly how things sorted out after the above events AND exactly how many planets we have. One got too close to Jupiter and broke up. That still leaves 14....

Answer 3

It's too simplistic to say they don't. The planets do revolve in a 3-D, but not generally in wild patterns.

The galaxy itself also is close to planar as well you'll notice. There are two ways that objects begin to orbit a central object, like the earth and planets orbit the sun. They can be broken off pieces of the central object, or they can capture that object after formation.

The reason that the solar system and the galaxy are more planar rather than all directions is because most of the objects in the solar system, and the galaxy came from the central object.

There are many exceptions to this, but a lot of the objects in the solar system are broken off pieces of the sun. When the big bang, or whatever caused the general expansion of the known universe happened, the big chunks formed and bits and pieces of those chunks broke off and started orbitting them.

There's no absolute way to prove this, so it's ok to be skeptical. It does follow model patterns of explosions in space, so it does have a bit of circumstantial going for it.

Answer 4

The planets move on the same plane because the sun itself is also rotating. Like if you swung a rope with a ball attached to it in circles. Your hand acts like the sun, rotating the planets (the ball) and the rope represents the suns gravity.
The models you've seen of electrons moving around the atom are meant to give a basic idea. Those orbits you see represent the the most likely place you will find an electron at any one time, not actual orbits.

Answer 5

I am under the impression that the planets rotate on different planes as you said up and down and that the models of the solar system are drawn on a parallel plan to simplify it.

Answer 6

This is a good question.

The planetary dust from which they were all formed rotated around the sun at the sun's equator in the same direction as the sun's rotation on its axis. Now, about Uranus which is off by several degrees, I have no idea.

Answer 7

Those diagrams aren't accurate, in either case. The planets don't share the same plane, and electrons don't orbit the nucleus in any sort of circular pattern.

Answer 8

The gravitational force of the sun and gravitational force of planet with each other makes them to revolve in the same plane.

Answer 9

They rotate in that direction because of the gravitation force of the sun.

Answer 10

They dont. The diagrams are too simplistic.
