• Based on Plot H, objects in the solar system with smaller/larger mass also have smaller/larger size.
ObservationsObservations
• 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 show a tight, positive correlation between mass and size.
• Based on Plot H, objects in the solar system have a narrow range of density.
ObservationsObservations
• Based on Plot I, objects in the solar system that have a large orbit tilt tend to have a more elliptical orbit shape.
