A bright star can appear dimmer than a less bright star if the bright star is?
If the bright star is located farther away from Earth than the less bright star, it will appear dimmer due to the inverse square law of light intensity. The amount of light reaching Earth decreases with distance, so a closer, less bright star can appear brighter than a further, brighter star.
What are the two factors that determine how bright a star looks from earth?
The two factors that determine how bright a star looks from Earth are its intrinsic brightness, or luminosity, and its distance from Earth. Stars that are more luminous will appear brighter, while stars that are closer to Earth will also appear brighter.
Is it true that two stars that have the same brightness are the same distance from earth?
Not necessarily. Two stars can have the same brightness but be at different distances from Earth. The distance of a star affects how bright it appears to us, so a closer dim star may appear as bright as a farther bright star.
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.
What is the difference between a star's brightness and luminosity?
The difference between apparent brightness and luminosity is that apparent brightness means that a star may appear to be bright, but only looks bright because of the relatively closeness a star is to earth. Luminosity is used by astronomers and refers to the power output of a star. Apparent Brightness means a star may appear to be very bright but only look that way because it is relatively close to Earth. Luminosity just refers to the power output of a star.

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 does Saturn look like from far away?
From Earth, it looks a lot like a bright star. From further away, it would appear as a dimmer star, or would not be visible at all.
What is difference between apparent brightness and absolute brightness?
Absolute Brightness: How bright a star appears at a certain distance. Apparent Brightness: The brightness of a star as seen from Earth.
Why does venus appear to be very bright from earth?
Earth's nearest neightbor
What two factors determine how bright a star looks from earth?
The two factors that determine how bright a star looks from Earth are its intrinsic luminosity (actual brightness) and its distance from Earth. Stars that are more luminous and closer to Earth will appear brighter in the night sky.
What are two ways to describe a stars brightness?
One way to describe a star's brightness is by its apparent magnitude, which is how bright it appears from Earth. Another way is by its absolute magnitude, which measures how bright a star would appear if it were placed at a standard distance of 10 parsecs from Earth.
