3. Mercury FUN FACT: Mercury’s sunny side has a temperature rising to 750° Fahrenheit. Mercury’s dark side, however, goes down to -328° Fahrenheit. Diameter: about 5,000 km Revolution: 88 days Rotation: 59 days Full of craters

4. Venus FUN FACT: Venus is named after the Roman Goddess of love and beauty. Diameter: about 12,000 km Revolution: 225 days Rotation: 243 days Atmosphere composed of sulphuric acid and CO2

5. Earth FUN FACT: The Earth is relatively fragile due to its moving tectonic plates. Diameter: about 12,000 km Rotation: What do you think? Revolution: What do you think? Only planet with conditions right for plentiful, liquid water

6. Mars FUN FACT: Mars has polar ice caps, which makes scientists wonder if life was once, or is, a possibility on Mars. Diameter: about 7,000 km Rotation: 24.6 hours Revolution: 687 days Surface covered in craters, volcanoes, and canyons

7. Jupiter FUN FACT: There is a permanent storm on the planet known as Jupiter’s Great Red Spot. Diameter: about 143,000 km Rotation: 10 hours Revolution: 12 years Made of Hydrogen gas, experiences huge oval-shaped storms

8. Saturn The rings are composed of small ice and rock particles FUN FACT: Saturn has at least 18 moons. Diameter: about 121,000 km Revolution: 12 years Rotation: 10 hours

9. Uranus Covered by a thick layer of gas and is surrounded by nine rings FUN FACT: As Uranus orbits the sun, it is laying on its side. Diameter: about 51,000 km Revolution: 84 years Rotation: 17 hours

10. Neptune Affected by harsh storm systems and is surrounded by five rings FUN FACT: This planet was not discovered until 1846. Diameter: about 50,000 km Revolution: 165 years Rotation: 16 hours

11. Questions For Class Discussion 1) As of 2008, Pluto is no longer considered a planet. Who knows why? 2) What planet is closest to Earth in size? In time spans of revolutions and resolutions? 3) If all planets were created at the same time, which planet has gone around the sun the most amount of times? The least? 4) How many times bigger is the biggest planet compared to the smallest planet? 5) A preview for the next lesson: What are some other components of our Solar System, besides the planets?
