Pluto's orbit is so eccentric that perigee (the point closest to the sun) is actually inside the orbit of Neptune.

And of course I stupidly used the wrong term for perihelion. Perigee refers to the closest point to EARTH not the SUN.

But at this distance, it is the same... -- Robert Heinlein

A little less the same than Heinlein's original context, though Pluto was involved there, too. Anybody catch the reference?

Your statement may still be correct, though.

Just stick with periapsis and thank Kerbel for making it easier to understand basic principles of orbits.
