Question

Quizplus · Accepted Answer

The spectral type of a star can be used to determine its surface temperature (A), color (C), and can be determined by identifying lines in its spectrum (D). However, spectral type alone is not enough to determine a star's distance. Other methods, such as parallax or measuring its apparent magnitude and comparing it to its absolute magnitude, must be used to determine a star's distance.
