I believe that the problem of how many planets with an orbit with a
given eccentricity
is not a real problem, if planetery system orbits are only designed to
describe certain
periodical phenomena! Clearly Kepler system is no more adequate once
it was discovered
the first dwarf planet, Ceres. Now the list of dwarf planet are more
consistent!
But how long planetary model system can be last based on possible
modification
of eccentricity coefficient?
This is really not the case.
It's more im****tant discover the star that through its expansion
produced our original nebula, but this is really hard
since that star is surely not visible!
