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 word means how bright a star appears?
The word you are looking for is "apparent magnitude," which is a measure of how bright a star appears to an observer on Earth. It is based on the star's intrinsic brightness and its distance from Earth.
What 3 factors affect how bright a star appears from earth?
The 3 factors that affect a star's brightness as viewed from earth, are: The star's age, distance from earth, and actual magnitude (scale a star's brightness is measured in).
Why can you see the moon so brightly?
The apparent brightness of any object depends on three factors. 1. Actual size 2. Distance 3. Actual brightness The Moon isn't especially bright; it doesn't shine on its own and the surface is gray dust, so it isn't all that good a reflector. But it's fairly large, and it is VERY CLOSE as celestial bodies go. The Moon is very bright because it reflects sunlight and is very close to Earth.
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.
Why is polaris considered to be a very bright star even though it is not a bright star in earths sky?
That refers to its actual brightness, not to how we see it. The apparent brightness depends on the real ("absolute") brightness, but also on the distance.
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.
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 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.
What is the apparent brightness of the stars?
Astronomers define star brightness in terms of apparent magnitude how bright the star appears from Earth and absolute magnitude how bright the star appears at a standard distance of 32.6 light-years, or 10 parsecs.
What 3 factors affect how bright a star appears from earth?
The 3 factors that affect a star's brightness as viewed from earth, are: The star's age, distance from earth, and actual magnitude (scale a star's brightness is measured in).
What is it called when the brightness of a star is measurable on a scale?
Star brightness is defined in terms of apparent magnitude, which is how bright the star appears from Earth. Star brightness is also defined by absolute magnitude, which is how bright a star appears at the standard distance of 36.2 light years. Luminosity is also a way that a star's light is measured.
In addition to the size an object in space appears which can be deceiving what other characteristic do scientists use to determine astronomic distances?
Scientists use the brightness of the object to determine its distance in space. By measuring how bright an object appears from Earth and comparing it to its actual brightness, they can calculate its distance based on the inverse square law of light.
Why can you see the moon so brightly?

What is the abstract noun for bright?
The abstract noun form for the adjective bright is 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.
