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.
A star brightness is called?
Apparent magnitude.
What is the apparent brightness of star vega?
The apparent magnitude of Vega is 0.03. The absolute magnitude is 0.58.
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.
What is the unit for apparent brightness?
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
What is the standard unit for apparent brightness?
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
What is a stars brightness as if it were a standard distance?
A star's brightness at a standard distance is referred to as its apparent magnitude. This standard distance is 10 parsecs (32.6 light-years) from Earth. Apparent magnitude allows astronomers to compare the brightness of stars as seen from Earth, regardless of their actual distance from us.
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 apparent brightness for Mizar?

What is another name for apparent magnitude?
brightness
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 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.
