I define a planet as anything Pluto or bigger that directly orbits a star.

Actually, if you look at the orbit, "our" moon actually orbits the sun, not Earth. The moon's orbit is always concave toward the sun. Sometimes (once each month) the curvature of the moon's orbit becomes more than the average curvature of the Earth-moon system, and the moon moves a bit further from the sun, but the moon's orbit never curves away from the sun, nor does it ever 'back up'. The same thing can be said of the Earth itself. In effect, we have a double-planet system.

Calling Luna a planet also meets the quoted definition of a planet, where the gravity overcomes the strength of material (round). Of course, there are a lot of 'moons' of Saturn and Jupiter that are round. In those cases the moons' orbits do curve away from the sun.

Maybe you need to expand your definition and say that it's a bigger than Pluto and is the largest object within a million miles.

I agree with you, and so does David Levy and Michael Brown. :')
