5 True/False questions

  1. Orion Belt StarsSpectral type O (white). Temperature range >30,000 K.


  2. Issues with Measuring ParallaxOne of the two major classes of variables. There are five classes. One important example: Cepheid Variables.


  3. ParsecThe distance to an object with a parallax angle of 1 arcsecond; unit is pc. One pc = 3.26 light years (ly) = 3.09 x 10^13 km.


  4. Absolute MagnitudeBrightness if we moved all the stars to the same distance. 10 pc. (Comparing apples to apples)
