That sure is a lot of questions in what ideally is a single question. There are four question marks, most of which each ask multiple questions. I suggest you do some research and then ask more pointed questions. Individually. A good place to start is to ask your favorite search engine about the stability of the solar system. You'll see several questions and answers on this topic at this site and at sister sites on the stackexchange network.

I asked a similar question on the Earth orbit here:   http://astronomy.stackexchange.com/questions/11243/how-has-the-earths-orbit-changed-over-hundreds-of-millions-or-billion-of-years

@DavidHammen   It's basically the same question just asked with different time periods and perhaps asked with some redundancy.  It's still basically one question and/or 2 very related questions.   What do we know about planets orbits over long periods of time and how accurate?

Fun fact, you can actually search for this on [Wolfram Alpha](http://www.wolframalpha.com/input/?i=position+of+the+planets+10000+years+ago), using phrases like "position of the planets 10000 years ago".  I tried it for 1 million, and it didn't have a result, so there appears to be a limit.  Also, I can't comment on the accuracy of the calculation.

@DavidHammen. Thank you for counting my question marks. I am sorry that I was not aware of the "one question mark only" policy at this site. I only just joined this forum in my quest to find an answer to this question and all my previous research was not successful. I will endeavour to mend my ways and edit my question accordingly.

it's a good question, **about how far** can you project?  say, 10 million years?

Might be a silly question but what does "N / i / w / a / e / M" mean?

How to calculate planetary position over vast time spans

# How to calculate planetary position over vast time spans

(Asked by: username_0 on 2016-12-08)

Ignoring the turbulent beginnings of our solar system I wonder if there is a meaningful way to calculate the relative position of the planets of our solar system 100 million years into the future using the standard parameters
N / i / w / a / e / M / +- pertubations , {assuming no unannounced black hole or neutron star zips through our solar system in the meantime.}
How far can the orbital calculations be projected into the future before error accumulation make these calculations completely meaningless?
