  5. One Way to Look at Things:Single Characteristics

  6. Observations • Based on Plot A, objects in the solar system …

  7. Observations • Based on Plot A, objects in the solar system generally have few moons.

  8. Observations • Based on Plot B, objects in the solar system …

  9. Observations • Based on Plot B, objects in the solar system generally have mostly circular orbits.

  10. Observations • Based on Plot C, objects in the solar system …

  11. Observations • Based on Plot C, objects in the solar system generally have low inclination orbits.

  12. Observations • Based on Plot D, objects in the solar system …

  13. Observations • Based on Plot D, objects in the solar system have a wide range of distances from the Sun.

  14. Observations • Based on Plot E, objects in the solar system …

  15. Observations • Based on Plot E, objects in the solar system have a wide range of masses.

  16. Observations • Based on Plot F, objects in the solar system …

  17. Observations • Based on Plot F, objects in the solar system have a wide range of sizes.

  18. Observations • Objects in the solar system • [A] generally have few moons. • [B] generally have mostly circular orbits. • [C] generally have low inclination orbits. • [D] have a wide range of distances from the Sun. • [E] have a wide range of masses. • [F] have a wide range of sizes.

  19. Relationships Between Characteristics It Takes Two to Tango:

  20. Observations • Based on Plot H, objects in the solar system …

  21. Observations • Based on Plot H, objects in the solar system with smaller/larger mass also have smaller/larger size.

  22. Observations • Based on Plot H, objects in the solar system with smaller/larger mass also have smaller/larger size. • Based on Plot H, objects in the solar system show a tight, positive correlation between mass and size.

  23. Observations • Based on Plot H, objects in the solar system with smaller/larger mass also have smaller/larger size. • Based on Plot H, objects in the solar system show a tight, positive correlation between mass and size. • Based on Plot H, objects in the solar system have a narrow range of density.

  24. Observations • Based on Plot I, objects in the solar system …

  25. Observations • Based on Plot I, objects in the solar system that have a large orbit tilt tend to have a more elliptical orbit shape.

  26. Observations • Based on Plot I, objects in the solar system that have a large orbit tilt tend to have a more elliptical orbit shape. • Based on Plot I, objects in the solar system show a loose, positive correlation between orbit tilt and orbit shape.

  27. The Plot Thickens:Size vs Composition

  28. Observations • Based on Plot J, objects in the solar system …

  29. Observations • Based on Plot J, objects in the solar system with similar composition have similar sizes.
