You'd think right but not quite. I think orbits are measured through the center of the planet so there is still the negligible distance of the planet and its atmosphere. However if you follow recent conventions pluto would lie outside our solar system under this system (what with it being no longer a planet - curse you astronomers!). It also eliminates any other non-planetary bodies that orbit beyond the final orbit.Alandoril said:Surely the end of our solar system is the orbital path of the last planet? I mean that would seem logical.
I think the best definition and the one their going with, is the area where the sun's gravitational pull is no longer the strongest gravitational force out there.
