9. Game Time Let’s compete and see who guesses it right! In each slide, you are to see a list of 5 facts about a planet. If you get it right after the first fact, you receive 50 points; the second fact, 40 points; the third, 30 points; the fourth, 20 points and 10 points when the final fact is shown. Ready?

10. The only planet never visited by a spacecraft Named after the Greek God of the Underworld The smallest in size Can sometimes be seen with a telescope Farthest planet from the sun

11. Known for its red color Named after the Greek god of Wars Extremely thin atmosphere Easily visible at night with the unaided eye The 4 th planet from the sun

12. Named after the Greek god of Agriculture Has extremely rapid rotation Has numerous very thin rings Easily visible because it doesn’t twinkle like the stars The 6 th planet from the sun

13. Gas planet Named after the Greek god of the Heavens Needs 84 years to complete one revolution around the Sun Barely visible with the unaided eye on very clear nights The 7 th planet from the sun

14. Old surface similar to the moon Named after the Greek god of Commerce and Travel Too close to the sun to be safely imaged Often visible at night with the unaided eye The Closest planet to the sun

15. Surface is very young Only planet whose name is not derived from Greek mythology Most of surface is covered with water Has only one natural satellite The 3 rd planet from the sun

16. By far the largest in size Named after the Greek King of the gods Huge, very strong magnetic field Often visible as the brightest star in the sky The 5 th planet from the sun

17. Appears blue in color Named after the Greek God of the sea Can occasionally be seen with binoculars Has very dark rings with unknown compositions The 8 th planet from the sun

18. Brightest planet Hangs a tale Named after the Greek goddess of Love and Beauty Usually visible at night with the unaided eye The 2 nd planet from the sun

19. More explorations on your own What is the origin of the solar system? How common are planetary systems around other stars? Is there life elsewhere in the solar system? If not, why is Earth special? Is there life beyond the solar system? Intelligent life? Is life a rare and unusual or even unique event in the evolution of the universe or is it adaptable, widespread and common?
