Praxis 5005 Practice Test Practice Question
Why does the Sun appear to be brighter than other stars?
Correct Answer: B
Rationale: The Sun appears brighter than other stars primarily because it is significantly closer to Earth than any other star, making its light more intense.
Option A is incorrect; the age of a star does not determine its brightness as perceived from Earth. Option C is misleading; while the Moon reflects sunlight, this does not affect the Sun's brightness relative to other stars. Option D is also false; although the Sun is large, it is not the biggest star in the universe. Many stars, like Betelgeuse, are much larger but are farther away, leading to less brightness from our perspective.
