  1. Planet Facts

  2. Planet Size

  3. Vocabulary • Surface Pressure (bars or atmospheres) - This is the atmospheric pressure (the weight of the atmosphere per unit area) at the surface of the planet in bars or atmospheres. • Length of Day - The average time compared to Earth for the Sun to move from the noon position in the sky at a point on the equator back to the same position.

  4. Mercury • Surface Pressure: 0 atm • Gravity: 3.7 m/s2 • Length of day: 175.9 • Diameter: 4879 km • Temperature: 167 C

  5. Mercury • Wind Speed: 0 • Atmosphere: virtually no atmosphere, however what is there contains hydrogen, oxygen, sodium, potassium and argon. • Water: yes • Other: most iron rich planet in the Solar System

  6. Venus • Surface Pressure: 92 atm • Gravity: 8.9 m/s2 • Length of day: 116.8 • Diameter: 12,104 km • Temperature:462 C

  7. Venus • Fastest Wind Speed: 1810 km/h • Atmosphere: mostly of carbon dioxide • Water: very little • Other: Billions of years ago, Venus probably had much more water.

  8. Earth • Surface Pressure: 1 atm • Gravity: 9.8 m/s2 • Length of day: 1 • Diameter: 12,756 km • Temperature: 15 C

  9. Earth • Fastest Wind Speed: 371 km/h • Atmosphere: nitrogen and oxygen • Water: yes • Other: contains life

  10. Mars • Surface Pressure: 0.01 atm • Gravity: 3.7 • Length of day: 1.03 • Diameter: 6792 km • Temperature:- 65 C

  11. Mars • Fastest Wind Speed: 93.2 km/h • Atmosphere: mostly carbon dioxide • Water: most is frozen • Other: Called the red planet because of the iron oxide on the surface.

  12. Jupiter • Surface Pressure: Unknown • Gravity: 23.1 m/s2 • Length of day: .415 • Diameter: 142,984 km • Temperature: -110 C

  13. Jupiter • Fastest Wind Speed: 620 km/h • Atmosphere: hydrogen • Water: trace amounts • Other: 63 moons
