Planet Nine, or Not?

Planet Nine, or Not?

45 minutes / For Older Children and Adults

Why isn't Pluto a planet anymore? What makes it different from the rest of the planets in our solar system? We'll answer these questions and more by visiting Pluto, Arrokoth, Haumea, Makemake, and more dwarf planets, trans-Neptunian objects, moons and asteroids in our solar system.

As we explore the universe, complete with visualizations based on the best NASA data available, we'll catch up on space missions and telescope projects aimed at the smaller members of our solar system. Be amazed at how much space all the moons of Jupiter and Saturn actually take up, and be puzzled at the weird orbits of the so-called irregular objects. Then we'll ask, should any of these things be classified as planets? Why or why not?
