I think Pluto is the only other planet with a tilted orbit plane. Thank public schools for the dumbed down science books for thinking the orbit is circular.

Nope. The Earth orbit plane is defined by convention as at 0.00. All other planets are tilted, Mercury and Pluto being the most extreme.

Well doesn't that mean that all planets are in the same plane except Mecury, Earth, and Pluto? The same except those extremes.
