Planets

  1. 1. The Planets
  2. 2. • The Solar System consists of the Sun and the astronomical objects gravitationally bound in orbit around it, all of which formed from the collapse of a giant molecular cloud approximately 4.6 billion years ago.• The Solar System is full of planets, moons, asteroids, comets, minor planets, and many other exciting objects.• Pluto is no longer considered as a Planet
  3. 3. Mercury• Average distance from the sun(million miles): 36• Average Temperature(C): 140• Diameter in km: 4900• Solid Planet:• Atmosphere: a thin layer of Helium• No moons• No rings• Length of a Day: 59 days• Length of a Year: 88 days• Surface Features: Craters, cliffs, dusty.
  4. 4. • It’s said that Mercurys orbit is being interfered with by another undiscovered planet.• There are no seasons on Mercury
  5. 5. Venus• Average distance from the sun(million miles): 67• Average Temperature(C): 450• Diameter in km: 12,100• Solid Planet• Atmosphere: Carbon Dioxide• No moons• No rings• Length of a Day: 243 days• Length of a Year: 225 days• Surface Features: rocky, canyons, dusty.
  6. 6. • Other than the Moon, Venus is the brightest natural object in the night sky• Venus is the only planet named after a female figure, the goddess of love.
  7. 7. Earth• Average distance from the sun(million miles): 93• Average Temperature(C): 10• Diameter in km: 12,800• Solid Planet• Atmosphere: Nitrogen and Oxygen• 1 moon• No rings• Length of a Day: 24 hours• Length of a Year: 365 days• Surface Features: water, mountains, volcanoes.
  8. 8. • Earth is not a perfect sphere, it is an oblate spheroid.• The moon is moving away from the earth at a rate of 4 cm a year.• Around 70% of water on Earth is locked within glaciers and polar ice caps
  9. 9. Mars• Average distance from the sun(million miles): 142• Average Temperature(C): -40• Diameter in km: 6,800• Solid Planet• Atmosphere: Carbon Dioxide• 2 moons• No rings• Length of a Day: 25 hours• Length of a Year: 687 days• Surface Features: Dunes, volcanoes, red dirt canyons.
  10. 10. • Scientists believe that Mars was once a very different place. Evidence points to volcanic activity, water and a rich atmosphere and warm climate.
  11. 11. Jupiter• Average distance from the sun(million miles): 484• Average Temperature(C): -150• Diameter in km: 143,000• Gas Planet• Atmosphere: Hydrogen, Helium• 63 moons• 4 rings• Length of a Day: 10 hours• Length of a Year: 12 years• Surface Features: Red spot, storms.
  12. 12. • One spot that planetary scientists think organisms could survive is Europa, Jupiter’s moon• The Great Red Spot is a gigantic storm.• Jupiter is the largest planet
  13. 13. Saturn• Average distance from the sun(million miles): 885• Average Temperature(C): -180• Diameter in km: 120,700• Gas Planet• Atmosphere: Hydrogen, Helium• 31 moons• 1000+ rings• Length of a Day: 10 hours• Length of a Year: 30 years• Surface Features: Storms, clouds.
  14. 14. • Another place where life could exist is Titan, Saturn’s largest moon.• Saturn has an average density less than water, that means it would float if there were an ocean big enough to hold it.• Saturn was the name of the Roman god of agriculture and harvest• The particles that make up Saturn’s rings range from the size of a grain of salt to the size of a mountain.
  15. 15. Uranus• Average distance from the sun(million miles): 1,781• Average Temperature(C): -200• Diameter in km: 51,800• Gas Planet• Atmosphere: Hydrogen, Helium• 27 moons• 11 rings• Length of a Day: 17 hours• Length of a Year: 84 years• Surface Features: Green, blue clouds.
  16. 16. • Uranus was the first planet discovered in modern history. It was also the first discovered using telescope.• The moons are named after characters of William Shakespeare and Alexander Pope.
  17. 17. Neptune• Average distance from the sun(million miles): 2,793• Average Temperature(C): -220• Diameter in km: 49, 500• Gas Planet• Atmosphere: Hydrogen, Helium• 13 moons• 4 rings• Length of a Day: 16 hours• Length of a Year: 165 years• Surface Features: Storms, blue clouds.
  18. 18. • Neptune is named after the Roman god of the Sea.• Neptune’s icy rings were discovered in 1968• Winds on Neptune can reach 2,000 km per hour –faster than the speed of sound.• The Kuiper belt, a large field of space debris is dominated by Neptune’s gravity.
