This business is a mess, and it's not science. Look at the image below and decide whether Pluto has "cleared its orbit" or not. NOTE: click on image for larger version.
It is clear everywhere by more than 2 Astronomical Units (the mean distance between the Earth and the Sun) from Neptune's orbit (its nearest neighbor), something that can't be said for Earth, Venus, Mercury, or Mars. Words like "overlaps" and "crosses" when applied to the orbits of Neptune and Pluto simply indicate that two dimensional geocentric thinking is going on.
