TRANSCRIPT
Inner Planets• Terrestrial Planets• Dense & Rocky• Smaller • Closer to the sun• Planets– Mercury– Venus– Earth– Mars
Outer Planets• Gas Giants• Large Planets• Massive atmospheres• Further from the sun• Planets– Jupiter– Saturn– Uranus– Neptune
Rotation v. Revolution• Rotation– 1 Full Turn on Axis– 1 Day
• Revolution– 1 Full Circle Around the Sun– 1 Year
Mercury: Closest to the Sun• 2nd Smallest• No True Atmosphere– Extreme Temperature changes– Hottest Planet
• 1 Day = 59 Earth Days• 1 Year = 88 Days
Venus: Earths Twin?
• 2nd Planet from the Sun• Size and Mass similar to Earth• Retrograde Rotation– Rotates opposite from Earth
• Densest Atmosphere– Mostly carbon dioxide = Toxic
• Slowest period of rotation– 1 day = 243 days– Takes more time to rotate around axis then to
revolve once around the sun
Earth: An Oasis in Space
• 3rd from the Sun• Abundant water and life• Atmosphere causes meteors to burn up
Mars: Red Planet
• 4th planet from the sun• Thinner atmosphere• Iron Oxide gives red color• Polar ice caps– Frozen carbon dioxide & water
Jupiter: Giant
• 5th planet from the sun• Largest planet• Atmosphere– Mostly hydrogen & helium
• Many Moons• Great Red Spot• Rotates the fastest– 1 day = 10 hours– High winds = Storms
Saturn• 6th planet from the sun• Thick outer atmosphere• Large Ring System– Icy particles
• Many Moons
Uranus: Tilted Planet• 7th planet from the Sun• Thin, dark rings• Blue-Green Color– Methane in Atmosphere
• Tipped on its side
Neptune: The Blue World
• 8th planet from the sun• Blue-Green Color• Dark Colored Storms• Layer of Liquid water under atmosphere• Very Narrow Rings• Strongest Winds
Pluto – Mystery “Planet”• Furthest “Planet”• Dwarf Planet• Smallest• Thin Atmosphere• Solid, Icy-Rock
