5 True/False questions
Main Sequence → Most stars, like our sun
Variable Stars → Stars that appear to change in brightness.
Spectroscopic Binary → Two stars that are so close that the only way we can detect the binary nature is through a spectral (red) shift.
Barnard's Star → Next closest after Proxima Centauri. 6 light years away. Next there are about 30 stars within 16.5 light years of earth.
Spectral type M → Red - Temperature range <3,500 K.
