Tilt of the Earth and Dates
• Earth rotates on its axis once every 24 hours
• Axis is tilted at 23 1/2 degrees
• Earth revolves around sun every 365 1/4 days in an elliptical path

Eclipses
Planets
• INNER PLANETS• Mercury• Venus • Earth• Mars
• OUTER PLANETS• Jupiter• Saturn• Uranus• Neptune
• Pluto
INNER PLANETS
• Terrestrial
• Small
• Solid
MERCURY
• Slightly bigger than the Moon
• Covered with craters
• 1 Mercury day is 59 Earth days
• -180 to 400° C
• 1 Mercury year= 88 Earth days
VENUS
• Covered with thick clouds
• Atmosphere is almost all CO2
• Surface temperature 475 °
• 1Venus day is 243 Earth days
• 1 Venus year is 225 Earth days
• Retrograde Rotation
EARTH
• Changing weather patterns
• Key to life is water
• Perfect distance from the Sun to support life
MARS
• Thin atmosphere of CO2
• Water only polar caps
• Covered in volcanoes
• Dusty, barren surface appears red
• 2 moons: Phobos and Deimos
• 1 day-1day 1year =687 days
• ½ diameter, 1/10 mass of Earth
OUTER PLANETS
• Gas giants
• No solid surfaces
• Pluto not considered an outer planet
JUPITER
• Made primarily of hydrogen and helium
• Giant Red Spot is a storm/tornado system the size of 1½ Earths
• Largest planet (able to hold all other planets)
• 60 known moons
– Io, most volcanically active place in solar system
– 3 of 4 large moons have icy surfaces
• 1 day = @ 10 hours 1 year = 11.9 years
SATURN
• Second largest planet
• Made of hydrogen and helium
• Winds blow 900 mph
• 31 known moons– Titan is larger than Mercury
• Rings are a few hundred meters thick and are the largest
– Can be seen from Earth with telescope
– Three main with thousands of ringlets
• 1 day = @ 10 hours 1 year = 29.5 years
URANUS
• Featureless, blue-green • Mainly hydrogen, helium, and methane
– Absorbs red part of sunlight• Rotates on its side
– Possibly struck by massive object• Has 13 rings • Has 27 moons
– Miranda shows evidence of being struck, breaking apart, and collecting together again
• 1 day = 17 hours 1 year = 84 years
NEPTUNE
• Made similar to Uranus with cloud belts• Great Dark Spot similar to Great Red Spot• Looks like faint blue-green star• Set of very narrow rings• 13 known moons
– Triton is smaller than Earth’s moon
– Orbits opposite of Neptune’s spin
• 1 day = 18 hours 1 year = 165 years
PLUTO
• Smallest
• rock and nitrogen ice with thin methane atmosphere
• Only planet never visited by a mission
• Sometimes orbit path is inside Neptune’s orbit making Neptune outermost planet
• One moon
– Charon is more than half the size of Pluto
• 1 day = just over 6 days 1 year = 248 years
