Pluto and Dwarf Planets

Pluto and Dwarf Planets

This tour explores bodies in our solar system that are too small to be classified as planets and too large to be comets. It answers the questions: What is a dwarf planet? Why isn’t Pluto a planet anymore? How was Pluto discovered? What are properties of the other known dwarf planets Eris, Ceres, Makemake and Haumea?  [5 min]
