What else can I help you with?
Which factor does not affect the apparent brightness of a star?
How old a star is.
A star brightness is called?
Apparent magnitude.
What is the apparent brightness of a star as represented by a number on a logarithmic scale?
The apparent brightness of a star is represented by its apparent magnitude, which is a logarithmic scale used to measure the brightness of celestial objects as seen from Earth. The lower the apparent magnitude number, the brighter the star appears in the sky. Each increase of one magnitude corresponds to a brightness factor of 2.5.
Use apparent magnitude in a sentence?
The apparent magnitude of a star is a measure of its brightness.
If the distance between us and a star is doubled the apparent brightness is decreased by a factor of four true or false?
True. The apparent brightness of a star is inversely proportional to the square of the distance between the star and the observer. So if the distance is doubled, the apparent brightness will decrease by a factor of four.
What is an apparent brightness?
An apparent brightness is the brightness of a star as measured by an observer.
A star's brightness is the brightness seen by humans on Earth. A star's brightness is its actual brightness and does not depend on where the star is viewed from.?
The brightness as seen from Earth is called the "apparent magnitude".The real brightness (defined as the apparent brightness, as seen from a standard distance) is called the "absolute magnitude".
What is the measure of the star's brightness?
The measure of a star's brightness is its magnitude. A star's brightness as it appears from Earth is called its Apparent Magnitude.Star's brightness is measured by there magnitude.
What is the apparent brightness for Mizar?
the apparent magnitude of the star mizar is -7.48 !
Why does a star look smaller than another star but is bigger than the other star?
Normally you would observe the star's brightness, not its apparent diameter.The star's apparent brightness ("apparent magnitude") depends on its real brightness ("absolute magnitude"), and on the distance. Similarly, the star's apparent angular diameter (which is VERY hard to measure) would depend on its actual diameter, and on the distance.
Which factor does not affect the apparent brightness of a star?
How old a star is.
A star brightness is called?
Apparent magnitude.

The apparent brightness of a star is represented by its apparent magnitude, which is a logarithmic scale used to measure the brightness of celestial objects as seen from Earth. The lower the apparent magnitude number, the brighter the star appears in the sky. Each increase of one magnitude corresponds to a brightness factor of 2.5.
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 a stars brightness as if it were a standard distance?
Theres `Absolute Magnitude` which is the brightness of a star at a set distance. Then there is `Apparent Magnitude` which is the apparent brightness from earth, regardless of distance.
Use apparent magnitude in a sentence?
The apparent magnitude of a star is a measure of its brightness.
What two factor affect a stars apparent brightness?
Two factors that affect a star's apparent brightness are: 1.) The distance between the Earth and the star 2.) The absolute magnitude (the actual brightness) of the star Hope that helps :P
