Planetary orbit problems again
-
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?

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[^]

I've thought about this before and my theory is: 1. Varying strengths of gravitational forces depending upon the plane in which something is orbiting is in (so everything over time settles into the gravitational plane where the strength is greatest), combined with.. 2. Everything that wasn't in that plane has at some point collided with another object and either merged with it, adopted the same orbit (according to rule 1) or been knocked out of orbit. That's just my guess though, if anyone knows better it'd be interesting to hear :)

it´s a feature of rotating bodies. it makes sense really, something in the ecliptical plane has sufficient speed (and thus force => centrifugal force) to counteract the force of gravity. The more above or below the ecliptical plane you are the less counterforce you have for the gravity and thus you fall into damnation (or into the planet). The rotation is caused similar to putting satellites into orbit. They still fall, but the speed is sufficiently large to miss the ground. And let that just be the knack of flying :-D . So basically it starts out as a "sphere" of debris, but only the debris in the ecliptical plane survives :). Hope this makes sense :)

Organizing Principle? There probably *were* other bodies going in various orbits at one time...they all collided, over and over, sometimes breaking up into smaller pieces which tended to follow the majority of bigger pieces (sometimes absorbing them due to higher gravity) that travelled in the same direction and on the same plane...eventually all that is left are things that occupy their own safe orbit on the same plane.

That looks like just the ticket! Unfortunately I need to wait until I get home to click the link. Doing so is not in the interests of my employer. :(

Space Weevils. They nest in rocks, and obviously grouped them together to make building nests easier... [In reality it's Conservation of Momentum: when gravity collapsed the original cloud the solar system was formed from, this caused the trivial spin it started with (the average "movement" of all molecules was in one direction or the other, a "zero-average" momentum is a very unlikely case) to increase in the same way that a ballerina pulling her arms inward spins faster. Once the mass is spinning "properly" a disk forms as it's the least-energy configuration. Same thing happens with planets and moons on a smaller scale.] But I prefer the Space Weevils.

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.

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.

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...
