2. Characteristics of Dwarf Planets:

  • Discuss the defining features of dwarf planets, such as their small size, lack of dominance in their orbits, and their diverse compositions.

3. Exploring Pluto:

  • Dive into the history of Pluto, once considered the ninth planet. Explore its composition, atmosphere, and the New Horizons mission’s discoveries.

4. Beyond Pluto: Other Dwarf Planets:

  • Introduce students to other dwarf planets like Eris, Haumea, and Makemake. Compare their characteristics and orbital patterns.

5. Small Bodies in the Kuiper Belt:

  • Explore the Kuiper Belt, a region beyond Neptune filled with small, icy bodies. Discuss how these objects contribute to our understanding of the early solar system.

6. Asteroids and Comets: Small but Mighty:

  • Learn about asteroids, rocky bodies found mostly in the asteroid belt, and comets, icy bodies with distinctive tails that originate from the outer solar system.

7. Impact on Earth:

  • Discuss the potential impact of asteroids and comets on Earth and the importance of studying these small bodies for planetary defense.
