Distance is one of three factors affecting the "apparent" magnitude of a star.
The other two are "absolute magnitude", or how bright it REALLY is, and the amount of dust and gas between the other star and our solar system.
For example, the closest star to Earth (other than our Sun, of course) is Proxima Centauri, 4.2 light years away. Proxima Centauri is NOT VISIBLE to the naked eye; it is a tiny red dwarf, so dim that you need a telescope to see it.
What else can I help you with?
Is a star brighter if it is closer to earth?
Yes, a star appears brighter if it is closer to Earth because the brightness of a star we see is affected by its distance. The closer a star is, the greater the amount of light that reaches Earth, making it appear brighter in the sky.
Is it true that the closer a star is to earth the brighter it appear?
That is one factor. The size of the star is the other.
What are Two reasons why one star would be brighter than another?
One reason could be that the brighter star is larger and hotter, emitting more light. Another reason could be that the brighter star is located closer to Earth, making it appear brighter in the sky.
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 does star Sirius appear brighter than star pollux?
Sirius appears brighter than Pollux because it is closer to Earth and is a more luminous star. Sirius is also a hot, blue star compared to Pollux, which is a cooler, orange giant star, further contributing to the difference in brightness.
Is a star brighter if it is closer to earth?
Yes, a star appears brighter if it is closer to Earth because the brightness of a star we see is affected by its distance. The closer a star is, the greater the amount of light that reaches Earth, making it appear brighter in the sky.
How can you tell if a star is brighter than another?
The star might be closer to the Earth, or it is just brighter than the others. :D
Why would a star that is farther than earth be brighter than a star closer to earth?

If two stars have the same absolute magnitude but one of the stars is farther from earth then the other one which star would appear brighter in the night sky?
The star that is closer to Earth will appear brighter in the night sky. Although both stars have the same absolute magnitude, the apparent brightness of a star decreases with distance. Therefore, the closer star will have a higher apparent magnitude, making it look brighter to observers on Earth.
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.
What is closer to the Earth the Sun or Polaris?
The sun is the closest star to earth.
Why does star Sirius appear brighter than star pollux?
Sirius appears brighter than Pollux because it is closer to Earth and is a more luminous star. Sirius is also a hot, blue star compared to Pollux, which is a cooler, orange giant star, further contributing to the difference in brightness.
What are two factors that determine the brightness of a star?
distance from the sun and the age of the star
How can a small star could look brighter from earth than a bigger star?
It would look brighter if it is closer to Earth. It is also possible for a small star (small in diameter) to have a higher surface temperature, i.e., to emit more light per square meter of its surface.
What are three physical factors that determine a star's brightness?
Three physical factors that determine a star's brightness are its temperature (hotter stars are brighter), size (larger stars are generally brighter), and distance from Earth (the closer a star is, the brighter it appears).
