1 BELL WORK What do you know about the planets in our solar system? Download today s keynote

2 THE PLANETS All time and distances in Earth calculations Objective: I can explain the relationship among common objects in the solar system, galaxy, and the universe. Essential question: What are the similarities and differences of the characteristics of our planets?

3 DENSITY This is a graduated cylinder with different liquids that have different densities. The more dense being on the bottom and the least dense being on the top. It depends on the density of the liquid whether it is will float or sink. Water s density is about 1g/cm3

4 SUN Distance from nearest planet: Distance from sun: Size: 865,000 miles Number of moon: 0 Number of rings: 0 Surface structure: Gaseous 100 times the Earth s diameter

5 SUN Average temperature:10,000f center 25,000,000F Density:1.4 g/cm3 Atmosphere: ball of gases Rotation(what direction does it spin): counter clockwise Rotation(spin on its axis how long): N/A Revolution(orbit around the sun): N/A

6 INNER PLANETS The 4 planets closest to the sun Inside the asteroid belt All Rocky/Terrestrial

7 MERCURY Distance to the nearest planet: Distance from sun: 35,983,095 miles Size(diameter): 3,032 miles Number of moons: 0 Number of rings: 0 Surface Structure: Rocky/terrestrial

8 MERCURY Temperature: 840 F on the side facing sun, 100s below freezing away from sun Density: g/cm3 Atmosphere: Hydrogen and helium Rotation(what direction does it spin): counter clockwise Rotation(spin on its axis how long): 1,407 hour and 30 minutes Earth time Earth day Revolution(orbit around the sun): 88 Earth days

9 IN YOUR NOTEBOOKS Why is there such a difference in the temperature of Mercury? Explain.

10 VENUS Distance from nearest planet:31,248,757 miles Distance from sun: 67, 232, 360 miles Size: 7,521 miles Number of moon: 0 Number of rings: 0 Surface structure: Rocky/terrestrial

11 VENUS Temperature: The thick atmosphere traps the sun's heat, resulting in surface temperatures over 880 F Density: 67 kg/m3 Atmosphere: carbon dioxide and clouds of sulfuric acid Rotation(what direction does it spin): clockwise Rotation(spin on its axis how long): 243 Earth days Revolution(orbit around the sun): 225 Earth days long

12 BELL WORK Explain why there are extreme temperature differences on Mercury and what three things make Venus so unique.

13 EARTH Distance from nearest planet: 25,724,767 miles Distance from sun: 93,000,000 miles Size: 7, 926 miles Number of moons: 1 Number of rings: 0 Surface structure: Rocky/ Terrestrial

14 EARTH Average Temperature: 45F Density: 5.51g/cm3 Atmosphere: nitrogen, oxygen, argon Rotation(What direction does it spin): counter clockwise Rotation(spin on its axis how long): 23hr 56minutes Revolution(orbit around the sun): days

15 IN YOUR NOTEBOOKS Is there a temperature difference between Venus and Earth? Why/why not?

16 MARS Distance from the nearest planet:78,340,000 miles Distance from sun: 141, 635, 300 miles Size: 4, 222 miles Number of moons: 2 Number of rings: 0 Surface structure: Rocky/Terrestrial

18 IN YOUR NOTEBOOKS What do all four of the inner planets have in common?

19 BELL WORK Answer on Bell work paper: What is the most unique characteristic about Venus?

20 OUTER PLANETS Called gas giants because they are made of mostly gases. Outside the Asteroid Belt Much colder

21 JUPITER Distance from nearest planet: 342,012,346 miles Distance from sun: 483, 632, 000 miles Size: 88, 846 miles Number of moons: 67 Number of rings: 4 Surface structure: Gaseous

22 JUPITER Average temperature: -244F Density: 1.33 g/cm3 Atmosphere: helium, hydrogen Rotation(what direction does it spin): counter clockwise Rotation(spin on its axis how long): 9hours 55 mins Revolution(orbit around the sun): 4, days

23 IN YOUR NOTEBOOKS How does the size of Mars compare to the size of Jupiter?

24 SATURN Distance from nearest planet: 401,592,178 miles Distance from sun: 888,188,000 miles Size: 74, 898 miles Number of moons: 62 Number of rings: several hundred thin rings Surface structure: gaseous

25 SATURN Average temperature: -300F Density:.687g/cm3 Atmosphere: hydrogen, helium, methane Rotation(what direction does it spin): counter clockwise Rotation(spin on its axis how long): 10hrs 13mins Revolution(orbit around the sun): 84.3 years

26 IN YOUR NOTEBOOKS What is significant(stands out) about the density of Saturn and the density of water? If we could put Saturn in a tub of water would it float or sink? Why?

27 URANUS Distance from nearest planet:900,377,530 miles Distance from sun: 1, 783, 950, 000 miles Size: 31, 763 miles Number of moons: 27 Number of rings: 13 Surface structure: gaseous

28 URANUS Average temperature: -300F Density: 1.27g/cm3 Atmosphere: ammonia, water, methane Rotation(what direction does it spin): titled at a 90 degree angle 42 Earth years of day and 42 Earth years of nights because of the tilt Rotation(spin on its axis how long): 17hrs 14mins Revolution(orbit around the sun): 84.3 years

29 IN YOUR NOTEBOOKS Why does Uranus have 42 years each of day and night?

30 NEPTUNE Distance from nearest planet: 1,011,297,430 miles Distance from sun: 2,798,842,000 miles Size: 30, 778 miles Number of moons: 14 Number of rings: 6 Surface structure: gaseous

31 NEPTUNE Average temperature: -370 Density: g/cm3 Atmosphere: hydrogen, helium Rotation(what direction does it spin): counter clockwise Rotation(spin on its axis how long): 16hrs 17 mins Revolution(orbit around the sun): 60,190 days
