Okay so I worked out that 3 Earth masses and 3AU is not a good combination - as the inclination for the ES never recovers and it gets ejected after about 6000 years and the rest of the inner system is ruined also.
Then I have another attempt at 2.2 Earth masses at 2.75AU...so far stable...
Thanks for the help!
Okay so I have 3 Earth masses at 3 AU - and it initally looks reasonally stable!
The e values are a bit higher than Mars [.04 to 0.5], but Mars itself remains stable, though the inclination creeps up all the time [1.7 and climbing very slowly]
-Possibly it looks...
Hello Tony,
Thank you for your interesting reply.
It is starting to sound like a series of encounters would be more plausible from a science and literary sense for my ES object...basically a keyhole approach initally in the past that sets the ES up for a Jupiter encounter in our times...
Yep, hence my earlier comment about a ES larger than Jupiter coming into the outermost limits of Pluto's orbit being bad news..so no BD [brown dwarves] in this story! :eek:
Jupiter is about 300 Earth masses, and the fictional ES is 3 to 4 Earth masses.
I have the fictional ES doing a...
A good point and something I should have mentioned...I have the ES planet as having been ejected from another star system undergoing a change from sole star to binary millions of years in the past.
The originating system also has a high angular moment relative to the galactic main...
