Stars Vocab

2. The second most basic element and the product of the majority of nuclear fusion reactions in stars
4. a star’s measured brightness compared to all other stars
6. An imaginary sphere of points and lines that astronomers created so they can all agree on where the stars are located. (Every known star is plotted somewhere on the celestial sphere.)
9. A chart used to organize stars by type, temperature, brightness, size, and color
10. The amount of matter that exists in a thing
11. A group of stars that appear to be next to one another in the night sky. Examples: Sagittarius, Gemini, Orion, Aquarius
13. A measurement of a star’s brightness. The greater the negative number, the brighter it is
14. The distance away from the celestial equator. (+/-) (Measured in degrees. Together with right ascension, these give the location of the star in the night sky. North Star’s declination = 89°15’50.8”
15. The amount of space that a thing takes up
16. The reaction that occurs in stars which provides a star with its power/shine/brightness

1. An extremely large star
2. The most basic element and the fuel for a star’s nuclear fusion reaction
3. A massive ball of gas that performs nuclear fusion in its core
4. a star’s brightness as observed from Earth
5. A small to a medium sized star
7. The fourth state of matter. In this state, electrons are stripped away from the atom due to high levels of energy
8. The distance away from the Vernal Equinox point (either moving to the right or left) in the celestial sphere. (Measured in Hours and Seconds. North Star’s Right Ascension = 02h 31m 49.1s
12. A measurement of a star’s brightness in watts; a calculation of how much power radiates
