Answer:

If the stars are about the same size and brightness then the earth must be nearer to the stat that appears brighter, The stars movement, nearer or farther, would only effect the frequency received (redshift).

Answer:

D- The earth is closer to the bright star

Step-by-step explanation:

If two stars have SAME brightness and size then that means the only point of difference is distance . Earth should be closer to the brighter star for the star to be bright.

I hope im right!!
