How can we determine the velocity of a star moving toward or away from Earth? a. By looking at the color of the star. b. By the shift of its spectral lines. c. By the brightness of the star. d. By its change in apparent size.

Hello!

Your answer should be B. By the shift of its spectral lines.

Explanation:

It is known that when studying space, to tell if a star is moving TOWARDS EARTH its measurements will move towards the RED side of the Spectrum...

MOVING AWAY will mean its measurements will move towards the BLUE end!

HOPE THIS HELPS!
