The father the star is away from the earth the more is is?
The farther the star is from Earth, the dimmer it appears to us. This is due to the inverse square law, which states that the intensity of light decreases in proportion to the square of the distance from the source. So, the greater the distance, the less light reaches Earth, making the star appear dimmer.
How can a star appear to become brighter and dimmer on a regular basis?
A star can appear to become brighter and dimmer on a regular basis if it is a variable star. Variable stars can pulsate, eclipse with another star, or vary in brightness due to other factors. By observing these fluctuations in brightness over time, astronomers can gain insights into the star's properties and behavior.
Why do stars appear brighter or dimmer?
Stars appear brighter or dimmer depending on their distance from Earth. The closer a star is, the brighter it appears, while stars that are farther away appear dimmer. Additionally, stars can also vary in brightness due to changes in their own luminosity or if they are being obscured by interstellar dust or gas.
How will a pulsating star appear when it is expanding?
A pulsating star will appear to increase in size and brightness as it expands and contracts rhythmically. This pulsation can cause the star to vary in luminosity over time, creating a characteristic pulsating pattern in its light output.
What brightness color of star?
The brightness and color of a star are related to its temperature and size. Hotter stars appear blue or white and are brighter, while cooler stars appear red or orange and are dimmer. The brightness of a star can also vary based on its distance from Earth.
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 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.
Describe relationship between the brightness and the distance of star from earth?
Due to the inverse square law, stars that are far away from Earth are generally dimmer than stars that are close to Earth. However, there are many exceptions, since stars can also appear brighter or dimmer depending on their luminosity.

Why isn't Polaris the brightest star?
How bright a star appears depends on how bright it is and how far away it is. While, on the whole Polaris is a very bright star it is also very far away, at least 350 light years, which makes it appear dimmer. The brightest star in the night sky is Sirius, one of the closest stars to Earth at only 8.6 light years. The brightest star overall, as viewed from Earth, is the sun, which is a quarter of a million times closer to us than the next nearest star.
What the relationship between magnitude and size of the star?
The brightness of a star depends on its temperature, size and distance from the earth. The measure of a star's brightness is called its magnitude. Bright stars are first magnitude stars. Second magnitude stars are dimmer. The larger the magnitude number, the dimmer is the star.The magnitude of stars may be apparent or absolute.
How bright does a star appear from earth?
It depends on its intrinsic brilliance and its distance from the observer
How will a pulsating star appear when it is expanding?
A pulsating star will appear to increase in size and brightness as it expands and contracts rhythmically. This pulsation can cause the star to vary in luminosity over time, creating a characteristic pulsating pattern in its light output.
How many times brighter will a star be than an identical star that's twice as far away?
4 times as bright. This is calculated as 1/22.
What brightness color of star?
The brightness and color of a star are related to its temperature and size. Hotter stars appear blue or white and are brighter, while cooler stars appear red or orange and are dimmer. The brightness of a star can also vary based on its distance from Earth.
