My last few days have been blighted with doubts about why things often seem to happen on a flat plain in space. As I understand it, which isn't very well, the planets orbit the sun on pretty much a flat plane. I'm wondering why this is, and why shouldn't there being planets going over and under the sun rather than obediently around it. (I think Pluto may make some vein attempt at this). I suspect the reason is the same for the rings of Saturn (why not a sphere) or Galaxies apparently also being quite flat. I have a number of theories, all crap. Anyone cast some light on this?

It's like gravity, Man. The big lumps are trying to fly away from the Sun, but they're also pulling each other together, so the only way they can go is to align on a plane.

Here you go: Why is the Solar System Flat?[^]
KeithBarrow.net[^] - It might not be very good, but at least it is free!
That's a very cute explanation of particle collapses. Shame it's not believed to be relevant to our solar system. Lookit: if one of the big lumps of our solar system were to decide to go off in a non-planar orbit (as they have many times in the past, through collisions, etc.), the gravity of all the other, lumps whizzing past them would slowly pull them back into the plane, and also "correct" their velocities. To avoid that, they would need something to give them a drastic change in velocity. So, the rule is: If you want to jump out of the plane, take a parachute.

The answer is simple. Me and Chuck Norris agreed it should be this way.

I only know that when I drink too much I go down flat and everything starts to orbit. :doh:

You are not drunk as long as you can still lie on the ground without holding onto something.

"I don't know, extraterrestrial?" "You mean like from space?" "No, from Canada."If you get sufficiently drunk and lie down, you will find the room rotates instead. There is a solution to this: tie the room down. Get some rope, tie one end to the room, and the other to the only stable thing in the universe - youself. A foot is good. Now when you lie down, the room will be unable to rotate because it can't drag you round and it all stays still. Try it, it works. Important note: try to remember about the rope round your ankle before you make a trip to the loo in the dark...

It looks like you're failing to undrestand the gravity of the situation. I always wear my coat, guess why?

Phww, you wouldn't know a planetary orbit even if you saw one from earth. :laugh: http://csep10.phys.utk.edu/astr161/lect/retrograde/aristotle.html[^]

well one can imagine a bunch of planet have the stupidest orbit around their sun.. indeed one planet in our solar system is not in the same plane as the other! http://cnx.org/resources/9e49b805527d2cdca109afcb51e660a9/graphics8.png[^] However solar systems begin as cloud of dust. Motes above that plane as they cross it / fall keep hitting motes from below the plan which are going up ending up nullifying each other. And when they finally merge into planets and suns, this process has already flattened everything!!

I think the key to Saturn's rings at least is accretion discs. I.e the material that makes up both the planet and its discs was a rotating mass before the planet formed. Once rotating, the equator of a body has a larger circumference than one that passes through each of the poles. This then helps to keep the rings bound to the same plane as the equator. Not sure about galaxies or solar systems though - however I suspect that similar forces are at play. -- On a side note, while looking for an answer I discovered that one of Saturn's moons is emitting some 1000kg/s of water vapour from it's South pole, which is then ionized and rotates around Saturn. Neat stuff. Thanks:thumbsup: http://en.wikipedia.org/wiki/Magnetosphere_of_Saturn[^]

That seems to me to require that body in question be an oblate spheroid.
