0.39 AU 6% of Earth’s Mass Mercury is an inner planet (terrestrial) No atmosphere, which causes extremely high day temperatures and extremely low night temperatures No moons BACK

0.72 AU 82% of Earth’s Mass Venus is an inner planet, sometimes called Earth’s sister planet Atmosphere is very dense, mostly carbon dioxide making temperatures and surface very hot No moons BACK

1 AU Mass = 6 x kg Earth is an inner planet Atmosphere that supports life 1 moon BACK

1.5 AU 11% of Earth’s Mass Mars is an inner planet Thin atmosphere that causes weathering and erosion, no liquid water on the surface of Mars 2 tiny moons BACK

TERRESTRIAL/INNER PLANETS - closest to the sun - rocky crusts and dense mantles and cores - atmospheres formed from gases that poured out of volcanoes (atmosphere can make a surface warmer and more uniform in temperature) - four types of processes that shape planets’ surfaces (tectonics, volcanism, weathering and erosion, impact cratering) - asteroids are also located in the inner solar system BACK

5.2 AU 318 Earth masses Jupiter is Gas Giant (outer planet) Fast winds and stormy weather, largest storm Great Red Spot 61 moons BACK

9.5 AU 95 Earth masses Saturn is a Gas Giant (outer planet) First planet known to have rings, use rings to see planet’s seasons 31 moons BACK

19 AU 15 Earth masses Uranus is a Gas Giant (outer planet) Seems to spin on its side, due to the axis of rotation being almost in the plane of its orbit 20 moons BACKBACK

30 AU 17 Earth masses Neptune is a Gas Giant (outer planet) Deep blue shade comes from methane gas in the atmosphere 11 moons BACK
