19. 1. Pluto is now considered a dwarf planet because it does not dominate its
neighbourhood. Its large “moon” is about half the size of Pluto, while all the
other planets are far larger than their moons. Another concern is the fact that
planets clear a path along their orbits, Pluto does not clear all the debris from
its orbital.
