1. Light moves pretty fast. How far can it travel in two years? (in km) 20 trillion km.

2. How far can light travel in 3 years? (in km) 30 trillion km

3. Why do we call it a light year? What does it have to do with "light" and a "year?" A light-year is a unit of distance. It is the distance that light can travel in one year.

4. Which three stars are closest to Earth? The Sun, Proxima, Alpha centauri

5. Which

6. Draw a simple HR Diagram. Label the X-axis in terms of hot and cold, and the y-axis in terms of bright and dim. i will turn this in on another paper

7. Label the main sequence, Sun, red giants, white dwarfs, and black dwarfs. is larger: 1 light year or 1 AU? Light year

8. Scroll down to the first colorful HR Diagram. Is Rigel or Sirius hotter? Which one is brighter? Rigel is hotter and larger

9. What percentage of stars on this diagram are colder than the Sun? Brighter? 31%

10. If we can't see black holes, how can we detect that they're even there? because the light bends

11. Can we see the event horizon of a black hole? No we are not able

12. What would it look like if you were to watch someone else fall into a black hole. Please include details of what you would see. If i saw mr. dunn fall in it would be so fast i would not see him he would be crushed

13. Why do pulsars pulsate?

1. Compare and contrast the geocentric and heliocentric models of the universe. Geocentric is when the earth is the center and heliocentric is when the sun is the then center which we believe in
2. Where, specifically, is the Sun in the geocentric model? it is forth a way from the earth
3. Whose theory had more planets represented: Aristotle's (and Ptolemy's) or Copernicus'? Aristitle's is because he count's the moon


4. Explain what retrograde motion is, and why it occurs. it happens by the orbit
5. Which planet(s) exhibit retrograde motion? Earth and Mars
6. As you can see from the picture, there are two different ways that retrograde motion can appear. Explain what accounts for the difference. by the orbit and the gravity


7. When you spin the Earth on the globe, are you modeling rotation or revolution? revolution
8. Which takes longer, one complete cycle of rotation or revolution? rotation
9. From the perspective of the North Pole, is the Earth rotation clockwise or counterclockwise? How about from the South Pole? Counter for north pole and clockwise for south


10. Diagram Earth as it orbits the Sun. Label the shape its orbit makes, Earth at perihelion, and Earth at aphelion.
11. Does Earth move faster at perihelion or aphelion? Why? the perihelion because you are the the orbit of the sun
12. About how much closer is Earth to the Sun at perihelion than it is at aphelion? (in miles) 91-95


13. When was perihelion in 2003? (date and time)Jan 4 05
14. When will aphelion occur in 2019? (date and time) July 4 22


15. Why do we have seasons? because the way it tiltes
16. As you may recall, the Summer Solstice is on or around June 21 each year. Worldwide (across the northern hemisphere anyway), when is the warmest day of the year? Why?

17. Which star is the North Star right now? polar
18. Which star will be the North Star in 26,000 years? polar
19. What is precession? when it rotates on it's axis

20. Write your own higher-level question about any topic from section 22.3 in your book. Answer your question.

What, specifically about your topic, are you going to research? the affects
What conclusions did you come to? What do you recommend average citizens do to make a difference? Be specific. This is the main part of your assignment. It could kill you so i think that we need to be care full and recycle them
What would happen if, worst-case scenario, nobody listened to your recommendations? Then i do it my was and get my grade
What would happen if, best-case scenario, everybody listened to your recommendations? Then we all work together and get an A

3. How is Mercury's internal structure similar to Earth's? it has volcanic activity
4. What is Venus' twin planet? Why do astronomers consider them twins? Earth similar in size, mass, composition, and distance from the sun
5. How is Venus different than its twin? it has no ocean's
6. Which planets do astronomers think contain life? Earth

9. What is the temperature range on Mars? (in Fahrenheit) -81 °F
10. Is Mars' atmosphere thick or thin? What is it made out of? it is thin it is made of carbon dioxide and argon
11. Jupiter's great red spot is a giant storm. How big is it? like earth
12. Is it a high or low pressure system? Is it a cyclone or anticyclone? Is it rotating clockwise or counterclockwise? it is a anti-cyclonic high pressure and it goes counterclockwise
