Thanks for setting me straight on that!
What is the tilt? 32 degrees?
wow, a little closer or further away and this planet would be intolerable.

Did I read somewhere that because of the elliptical orbits of Neptune and
Pluto that they
actually change places in their relationship to the sun? meaning,

sometimes
Pluto is no the farthest planet?


Neptune's orbit is almost circular, most planets have nearly circular
orbits, the exceptions are mercury and Pluto. Yes, when Pluto is around its
perihelion (closer to the sun), its orbit is inside the orbit of Neptune.
Last time that Pluto was closer to the sun than Neptune was from 1979 to
1999, next time will be from about 2228 to 2248.
