5 True/False questions
Orion Belt Stars → Spectral type O (white). Temperature range >30,000 K.
Issues with Measuring Parallax → One of the two major classes of variables. There are five classes. One important example: Cepheid Variables.
Parsec → The 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.
Absolute Magnitude → Brightness if we moved all the stars to the same distance. 10 pc. (Comparing apples to apples)
Stellar Mass → Spectral type F (pale yellow) Temperature range: 6,000-7,500 K.
