Demotions In The Solar System
In the 1990s, scientists demoted Pluto from being a planet to being known as a Kuiper Belt Object. Sometime before poor Pluto got stripped of its title, Ceres, another body formerly known as a planet, was reclassified as part of an asteroid belt. But then, in 2006, scientists bumped back Ceres and Pluto and assigned them the category of “dwarf planets”.
