Name: ______________________________________________________ Explain how each of the 5 characteristics in the boxes below is used to classify stars. In each box, give 2 examples of stars and their specific characteristics. Use pages 127-129 in the textbook and the examples below to complete the worksheet. Size Stars vary greatly in size. Some sizes of stars are: Example 1: The Sun is a medium sized star. Example 2: Temperature Color Explain how temperature can be used to classify a star: Example 1: The temperature of the Sun is: Example 2: Explain how color can be used to classify a star: Stellar Classification Example 1: The star Betelgeuse is the color: Example 2: Brightness The brightness of a star depends on size and temperature. A star’s brightness can be determined using: Apparent brightness- Composition (make-up of star) Stars vary in their chemical composition. Most stars are made of: Absolute brightness- Spectrograph: Example 1: Example 1: Example 2: Example 2:
