Grouping PlanetsGrouping PlanetsTwo other ways to group planets:

1.Composition- what the they’re made of -Rocky planets: Mercury, Venus, Earth,

Mars, Pluto*heavy, move slowly, no rings, few

moons

-Gas planets: Jupiter, Saturn, Uranus, Neptune

*light, move quickly, rings, lots of moons

2.Size -Small: Mercury, Venus, Earth, Mars,

Pluto -Giant: Jupiter, Saturn, Uranus, Neptune
