  1. This is fascinating, but please do not blindly accept the controversial demotion of Pluto as fact when it is not. It is just one interpretation, adopted by four percent of the IAU, most of whom are not planetary scientists, and it was opposed in a formal petition by hundreds of professional astronomers led by New Horizons Principal Investigator Dr. Alan Stern.

    Pluto and Haumea are both small planets because they are spherical, meaning they are rounded by their own gravity, a condition known as hydrostatic equilibrium, and they orbit the sun. This definition gives our solar system 13 planets and counting: Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto, Haumea, Makemake, and Eris.
