What is an apparent brightness?
An apparent brightness is the brightness of a star as measured by an observer.
What is the brightness of a star as you see it in the night sky is?
Apparent magnitude
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 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.
Which factor does not affect the apparent brightness of a star?
How old a star is.
A star brightness is called?
Apparent magnitude.
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.
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.
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.
Use apparent magnitude in a sentence?
The apparent magnitude of a star is a measure of its brightness.
