1. Astronomy Review Jeopardy

2. Planet Earth is located in this galaxy.

3. What is the Milky Way.

4. These features of our planet are the reasons we have seasons.

5. What are 23.5° tilt of axis and rotation around the sun.

6. This large number can be represented in scientific notation: 2710000000.

7. 2.71 x 109

8. This can tell us a star’s temperature and what elements are in the star.

9. What is the “colour” of the star.

10. This planet is closest to our sun.

11. What is Mercury.

12. This is the approximate age of our sun.

13. What is 4.5 billion years.

14. Two stars orbiting each other is called this.

15. What is a “binary star”.

16. This causes the tides of our oceans.

17. What is the gravitational pull from the Earth to the moon.

18. 1.496 x 108 Km = ?.

19. What is 1 AU (astronomical unit).

20. What is meant by Red Shift and what does it explain?

21. When the colour spectrum of stars have shifted to the red-end over time; this provides evidence that the universe is expanding (presumably from the centre where the “big bang” must have occurred).

22. This element forms when hydrogen molecules fuse.

23. What is Helium.

24. This celestial body is made of rock and ice.

25. What is a comet.

26. A gas cloud where stars are born.

27. What is a nebula.

28. This disrupts satellite communications, but also enhances our Northern Lights.

29. What are “solar flares”.

30. Mars has a slower and larger orbit around the sun, which makes it sometimes look like it is travelling backwards in our sky… this phenomenon is called...

31. What is “retrograde motion”.

32. Helium undergoes fusion to form Carbon, turning a medium mass star into this form.

33. What is a Red Giant.

34. This is the type of star that forms after a red giant collapses.

35. What is a White Dwarf.

36. Jupiter is about 778330000 km away from the sun
Jupiter is about km away from the sun. Using the conversion of 9.46 x 1012 km = 1 ly, calculate how many lightyears that is. Put your answer in scientific notation and round to two decimal places.

37. 8.23 x 10-3 ly
