Question

question 4 of 10. why do astronomers find it difficult to locate extrasolar planets with telescopes? a. gravitational pull from stars causes revolving planets to wobble. b. light from the stars they orbit makes it difficult to see them. c. planets reflect their suns light in all directions.

Explanation:

Extrasolar planets are much dimmer than the stars they orbit. The intense light from the stars outshines the faint light reflected by the planets, making them hard to detect directly. Option C is correct as the light from the star overwhelms the reflected light of the planet coming from all directions, making it difficult to distinguish the planet. Option A refers to the wobble - method used to detect planets rather than the difficulty in direct - visual location. Option B is incorrect as the wobbling is a sign used to detect planets, not a reason for difficulty in visual location.

Answer:

C. Planets reflect their sun's light in all directions.
