 * Planet || Dwarf Planet ||
 * Needs to orbit the Sun || it has to have sufficient mass to overcome its compressive strength and achieve hydrostatic equilibrium ||
 * Needs to have enough gravity to pull itself into a spherical shape || Rounded by it's own gravitational pull ||
 * Needs to have “cleared the neighborhood” around it || Has not “cleared the neighborhood” around it ||


 * hydrostatic equilibrium occurs when compression, caused by gravity, is balanced by a pressure gradient, which creates force in the opposite direction. The inward pressure is counteracted by the external pressure of the atmosphere.
