![The right y-axis of the HR diagram on page 2 is
absolute magnitude (Mv). Absolute magnitude is the
apparent magnitude a star would have if it were 10
parsecs away from Earth. For the magnitude scale, the
brighter the star, the smaller the magnitude, e.g., a 3rd
magnitude star is brighter than a 4th magnitude star.
For each of the stars below, determine its absolute
magnitude from its position on the HR diagram. Rigel
