How bright would the sun appear to be to an observer on Earth if the Sun were four times farther from the Earth than it actually is?

The sun would be 4 times less bright than it is now. The brightness of the sun follows an inverse square law

A bright star can appear dimmer than a less bright star if the bright star is?
Farther away!
Why are other stars not bright like the sun?
The other stars do not appear as bright as the sun because they are much farther away. Even the closest stars apart from the sun are hundreds of thousands of times farther away. In terms of actual brightness, some stars are brighter than the sun.
Is the closer a star is to earth the brighter it is?
Yes. A star that is closer to us will appear brighter than if it were farther away. However, stars also vary in their actual brightness, so how bright a star appears depends on both how far away it is and how bright really it is.
Why The Moon and the planets appear bright at night?
they appear bright be cause the light from the sun is hitting the moon and planets to make them look bright.
Why Some stars appear to shine more brightly than the others?
The stars vary in both how far away they are and in actual brightness. The closer a star is to us, the brighter it will appear. Stars also vary in actual brightness. For example, the brightest star in the night sky is Sirius. It appears bright because it is both a fairly bright star (about 25 times brighter than the sun) and is one of the closest stars to us at 8.6 light years away. The nearest star visible in the night sky, Alpha Centauri, is about half that distance but does not appear as bright because it is far less bright than Sirius in actual luminosity. Conversely, Sirius also appears brighter than Betelgeuse which is actually much brighter than Sirius but also much farther away.
A bright star can appear dimmer than a less bright star if the bright star is?
Farther away!
How bright does a star appear from earth?
It depends on its intrinsic brilliance and its distance from the observer

How can a star give off the most light and not be the brightest in the sky?
How bright a star appears depends on both its actual brightness and how far away it is. The farther away a star is, the dimmer it appears. A bright but very distant star many therefore appear dimmer than a less bright star that is closer to us.
What is the relationship with brightness and distance with stars?
Other things being equal, if a star is farther away, it will look less bright. This is the same with any light - if you move farther away from the light, it looks less bright.

How does the sun appear to you?
um really bright
Why stars are not as bright as the moon?
In terms of actual brightness the stars are much brighter than the moon and some are even brighter than the sun. They only appear dim because they are much farther away than either the sun or the moon.
Why does the sun look so bright?
The main reason that the sun appears so large and bright to us is that we're soclose to it. The next nearest star is about 270 thousand times farther away thanthe sun is, and all the others are even farther than that.
What causes the moon to appear in the bright sky?
light on the sun
