1. By looking at a star’s spectra, one can tell what _____________________make up
the star.
2. Describe the life cycle of an average star like our sun.
3. Describe the life cycle of a HIGH mass star.
4. Name the planets in their order from the sun.
5. Circle the correct answer.
The closest star is the (Sol, Proxima Centauri).
When the moon gets smaller every night it is (waxing, waning).
Thermonuclear (fusion, fission) converts hydrogen to helium.
When our sun starts to die it will become a (red giant, black hole).
On the HR diagram, stars on the bottom left are (hot and dim, cold and dim).
6. Color in and label these phases of the moon. Make them reflect the shape of
their names. Ex. Crescent shaped. 15 points
waxing
waning

7. Sequence The events in the life cycle of a star are not given in the correct order. Write the
correct number of the numbered statements on the line provided.
1. A black dwarf forms
4. A protostar forms in a nebula
2. A white dwarf forms
5. A main sequence star
3. A red giant forms
1. These are Kepler's Laws of Planetary motion. Put the correct number in front
of the law. (1, 2, or 3)
Law _____:Each planet moves in an elliptical orbit having the sun at one focus.
Law _____: The square of any planets period is proportional to the cube of the planets average
distance from the Sun.
Law _____: An imaginary line from the sun to any planet sweeps out equal areas in equal time
intervals.
Circle the correct answer.
12. White dwarfs are very hot stars that have (high, low) absolute magnitudes.
13. Main sequence stars are stars that fit into a (diagonal, vertical) band that runs from the
upper left to the lower right on the diagram.
14. Although its temperature is greater, our sun has a lower absolute magnitude than that of
(Betelgeuse, Vega).
15. On the diagram, our sun is identified as having an absolute magnitude of about (-5, +5).
16. Supergiants are stars with relatively (high, low) temperatures and high absolute magnitudes.
17. Red giants (are, are not) main sequence stars.
18. The absolute magnitude of Rigel is (higher, lower) than that of the sun.
19. Betelgeuse is (hotter, colder) than Rigel.
20. The temperature of Rigel is (hotter, lower) than that of the sun.
21. Betelgeuse has an absolute magnitude that is (greater, less) than that of Rigel.
22. A star that lies outside the main sequence is (Rigel, Antares).
23. White dwarfs and red giants lie (outside, inside) the main sequence.
