It seems like you're trying to ask: "The farther a star is from Earth, the _______ it is?"
To complete the sentence, you need to understand the relationship between a star's distance from Earth and its brightness. Here's the explanation:
* The farther a star is from Earth, the dimmer it appears.
This is because the light from a star spreads out as it travels through space. The farther the star, the more the light spreads, resulting in a fainter appearance.
So the complete sentence would be:
"The farther a star is from Earth, the dimmer it appears."
