- Absolute Magnitude
- a Pale Yellow - Temperature range: 6,000-7,500
- b White star - Temperature range >30,000 k.
- c Brightness if we moved all the stars to the same distance. 10 pc. (Comparing apples to apples)
- d A Star's total amount of power radiated into space; measured in watts
- e Everything is moving. Overcome by making more than two measurements, take all motions in account, now calculate parallax then distance.

5 True/False questions
Spectral type K → Orange - Temperature range: 3,500 - 5,000 K.
Binary Stars → Systems in which physically associated star systems are made up of two stars.
Pulsating Variables → One of the two major classes of variables. There are five classes. One important example: Cepheid Variables.
Spectral type G → Yellow - Temperature range: 5,000 - 6,000 K.
Parallax → The apparent shift of an object relative to some distant background as the observer's point of view changes. Allows you to determine close stellar distances. Only works with fairly close stars
