What is Pluto?
Pluto is a dwarf planet located in the outer regions of our solar system. It was once considered the ninth planet in our solar system, but in 2006, the International Astronomical Union reclassified Pluto as a dwarf planet due to its size and its orbit crossing with Neptune's.
Characteristics of Pluto
Pluto is a small, rocky world with a thin atmosphere. It has a highly elliptical orbit that takes it closer to the sun than Neptune for a portion of its orbit. It has five known moons, the largest of which is Charon.
Study Guide
- History: Research and write a brief history of Pluto, including its discovery and reclassification as a dwarf planet.
- Physical Characteristics: Describe the physical characteristics of Pluto, including its size, composition, and atmosphere.
- Orbit and Moons: Explore Pluto's orbit and its five moons. Create a diagram to illustrate its orbit and the moons' positions.
- Comparison to Planets: Compare and contrast Pluto with the other planets in our solar system. What sets it apart from the others?
- Exploration: Research any spacecraft missions or future plans to explore Pluto. What have we learned from these missions?

PHYSICAL SCIENCE
Motion and Stability: Forces and Interactions
Investigate the resulting motion of objects when forces of different strengths and directions act upon them (e.g., object being pushed, object being pulled, two objects colliding).
Use observations and data from investigations to determine if a design solution (e.g., designing a ramp to increase the speed of an object in order to move a stationary object) solves the problem of using force to change the speed or direction of an object.
LIFE SCIENCE
Ecosystems: Interactions, Energy, and Dynamics
Distinguish between living and nonliving things and verify what living things need to survive (e.g., animals needing food, water, and air; plants needing nutrients, water, sunlight, and air).
