Question

HELPPP BESTIESSS An astronomer is studying two stars that have about the same size and brightness. From the Earth, one of the stars appears very bright in the night sky. The other star appears very faint and dim.

A. The Earth is moving toward the brighter star.
B. The Earth is moving toward the dimmer star.
C. The Earth is farther from the brighter star.
D. The Earth is closer to the brighter star.

Answer 1

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 2
