Is evolution of solar planetary system chaotic?

[pranab]

Chaos is a mathematical concept that has been described here as we understand it" Deterministic randomness" meaning that a chaotic system is deterministic but so complicated. The random chaos theory tell us it is impossible to predict the long term behavior of very complex dynamic system, because all of conditions are not known with precision at any time and uncertanity increases with a time.
The evolution of the entire solar planetary system had been when numerically intregrated for a span of nearly 100 million years, the calculation confirms the evolution of of the system as a whole is chaos with a time scale of ex potential divergance of only about 5 million years[ J. Laskar Nature 338;237;1989] Sussman & Wisdom presented numerical evidence that motion of pluto is also chaos with a time scale for expotential divergance of nearby tragectors of only 20 million years[ GJ Sussman & J Wisdom- science 241;433;1988] what did realy happened in evolution of solar planetary system- chaotic over 100million years? is there any consequences of observed chaotic evolution of solar system? what was the basic mechanism for generating such a chaotic behaviour-?

Only one answer to that, it's not a basic mechanism.

One theory that I know of, has very small particles and, gas left over after our Sun formed, bumping into each other and settling in the middle of the Solar System's dusty and gaseous disk, they then became lumpy or gravitationally bound and grew over time.

This resulted in utter chaos, as they grew, into rubble piles, they accrued even more matter, and then eventually started perturbing each others Orbits as they were growing, and reaching Planetary size, Gravity became a big factor in shaping what we now know as our System,
smashing themselves into bits or sending other large and small objects toward the sun or ejecting them out of the early Solar System.

The evidence the theory uses as support is all of the impact cratering that has been found on all the Rocky Planets and their Moons, from all of the probes that have been sent to study and photograph the Planets.

The fact is, that we really don't know for sure how many mechanisms were involved in the formation of our System, but I would assume it was not attributed to one basic mechanism.

We could have even captured some objects or moons as the planets were forming, also take into account that we really don't know what happened in the past, when the Planets were forming, such as Galactic Orbital Oscillations or, other Galactic debris, Gas, and the Gravitational effects of Passing Stars as we revolved around the Galaxy and evolved into what we see today.

Basically two mechanism we think might play in the chaotic evolution of solar planetary system when we consider evoltion in time scale 100 million years are that- simultenious presence of two different expotential time scale in our full solar system integration generated chaos or massive jovian planets themselves evoved chaotically and pluto is independently chaotic in the feild of jovian planets

Hi Pranab,
Since Pluto has an Orbit completely different form the rest of the planets In other words its not orbiting along the Solar systems Accretion disk ,Isn't it quite possible that it may have been captured due to the early chaotic beginnings of our system, by Gravitational perturbations or, a trajectory change due to an Impact?

Thing is other planets also have done this and they have regular orbits...

[dmill1220]

Hi Dragon,
do you mean that other Planets have also captured Moons?
or, do you mean that other planets have also been captured by our Solar System?

Planets, actually. It's not fact, but it explains distant planets such as Pluto, Sedna, exc...

Here is one senerio.

Hi Dragon!
Read your link completely that you gave me,it says
sedna and the others do not orbit in the same plane as ours.
But its exactly what I was Proposing since the orbital periods and inclination are not within the Sun's Acretion disk.
ITs a very interesting possibility a Chaotic scenario where not only our own several worlds were colliding and sending some into the Sun or out of the Solar Sytem but also gravitational tugs from Galactic Oscillations by Passing stars or a Unseen Nemesis Star in our Orbit around our Galaxy.

there could have been many more planets before gravity and collisions wreaked havoc on all the newly formed Planets or Smaller objects.

Dear Danis Mill
I Hope You are correct. In science, we can not often say " Yes 100%Correct" as in science theories are often changing. So near to correct- Thanks
