Title: The Planets of the Solar System


1
The Planets of the Solar System
  • A Trip Through the Solar System

2
Mercury - named after the speedy messenger of the
Roman gods
  • Closest planet to the sun
  • Revolution around the sun 88 Earth days
  • Rotation on its axis 59 Earth days
  • Crater-covered surface with steep cliffs
  • Almost no atmosphere
  • Temperature range
  • as high as 427 degrees C
  • as low as -170 degrees C

4
Venus - named after the Roman goddess of beauty
and love
  • Second planet from the sun
  • About the same size as Earth
  • Thick, cloudy atmosphere
  • sulfuric acid
  • carbon dioxide
  • Temperature range
  • as high as 480 degrees C

5
Venus - named after the Roman goddess of beauty
and love
  • Surface pressure 91 times more than Earths
  • Surface has
  • deep canyons and tall mountains
  • craters
  • vast plains
  • Revolution around the sun 224 Earth days
  • Rotation on its axis 243 Earth days

6
Venus - named after the Roman goddess of beauty
and love
  • Greenhouse effect
  • heat becomes trapped beneath the clouds
  • results in little or no water on Venus surface

8
Earth
  • Third planet from the sun
  • Revolution around the sun 365 days
  • Rotation on its axis 24 hours
  • Because the axis of the Earth is tilted, this
    creates distinct seasons throughout the year

9
Earth
  • Temperature range depends on the location,
    altitude and season
  • Gravitation pull of the moon creates tide changes
    (rise and fall of the ocean levels)
  • Surface -
  • Mountains
  • Plains
  • Deserts
  • Heavy vegetation

10
Earth

11
Mars - named after the Roman god of war
  • Fourth planet from the sun
  • Surface
  • rocky
  • large craters
  • soils is similar to Earths soil in many ways
  • four large volcanoes (dormant)

12
Mars - named after the Roman god of war
  • northern ice cap
  • frozen water
  • southern ice cap
  • frozen carbon dioxide
  • Very thin atmosphere
  • High winds often create dust storms
  • Temperate falls well below 0 degrees C all the
    time

14
Jupiter - named after the king of the Roman gods
  • Fifth planet from the sun
  • Largest planet
  • Made of mainly
  • hydrogen
  • helium
  • Temperature range -
  • very cold at the cloud tops
  • as high as 30,000 degree C at the core

15
Jupiter - named after the king of the Roman gods
  • Atmosphere
  • hydrogen
  • helium
  • ammonia
  • methane
  • Great Red Spot
  • hurricane-like storm (as much as 20,000 years old)

16
Jupiter - named after the king of the Roman gods
  • Very high atmospheric pressure
  • Giant magnetic field
  • created by the liquid metallic layer
  • called magnetosphere

18
Saturn - named after the Roman god
  • Sixth planet from the sun
  • Surrounded by rings
  • made of icy particles
  • has at least seven major rings
  • Made of mainly
  • hydrogen
  • helium

19
Saturn - named after the Roman god
  • Violent atmospheric storms
  • Very cold
  • Has a large magnetic field
  • Lowest density of all the planets

21
Uranus - named after the father of Saturn in
Roman mythology
  • Seventh planet from the sun
  • Atmosphere
  • hydrogen
  • helium
  • methane
  • Temperature range
  • as low as -220 degree C at the cloud tops

22
Uranus - named after the father of Saturn in
Roman mythology
  • Extreme atmospheric pressure
  • atmosphere is 11,000 kilometers thick
  • Rotates on its axis at a 90 degree angle
  • appears laying on its side
  • Rings of methane ice surround it

24
Neptune - named after the Roman god of the sea
  • Eighth planet from the sun
  • Atmosphere
  • hydrogen
  • helium
  • methane
  • Temperature
  • as low as -220 degrees C

25
Neptune - named after the Roman god of the sea
  • Surface
  • ocean of water and liquid methane
  • rocky core
  • Five rings surround Neptune
  • made of dust particles formed from meteorites

27
Pluto - named after the Roman god of the
underworld
  • Ninth planet from the sun
  • Smallest planet
  • Least dense planet
  • Seems to be made primarily of methane ice
  • Thin atmosphere (only on the sunny side)
  • methane ice evaporated to form this
