question 5 of 10
why do astronomers find it difficult to locate extrasolar planets with telescopes?
a. extrasolar planets are not bright compared to the stars they orbit.
b. there is no life on extrasolar planets.
c. extrasolar planets are much colder than earth.

Explanation:

Extrasolar planets only reflect the faint light of their host stars, which are vastly brighter. This extreme brightness difference makes it hard for telescopes to distinguish the dim planets from the overwhelming glare of the stars they orbit. The presence of life or planetary temperature does not impact the direct detectability with telescopes in this context.

Answer:

A. Extrasolar planets are not bright compared to the stars they orbit.
