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
What else can I help you with?
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.
How does apparent magnitude of a star differ from absolute magnitude?
Apparent magnitude is the brightness as observed from earth, while absolute magnitude is the brightness of a star at a set distance. The apparent magnitude considers the stars actual brightness as well as it's distance from us, but absolute magnitude takes the distance factor out so that star brightnesses can be directly compared.
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.
What the measure of a stars brightness called?
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 A star's level of brightness as viewed by the unaided eye?
A star's brightness as viewed by the unaided eye is measured using its apparent magnitude, which quantifies how bright a star appears from Earth. The scale is logarithmic, meaning a difference of 5 magnitudes corresponds to a brightness factor of 100. Stars with an apparent magnitude of around 6 or lower can typically be seen without telescopes, while brighter stars have lower magnitude values. For example, the brightest stars in the night sky, like Sirius, have apparent magnitudes of around -1.46.
What is a stars level of brightness as viewed by the unaided eye called?
Apparent magnitude.
What stars level of brightness as viewed by the unaided eye is called?
Apparent magnitude.
A stars level of brightness as viewed by the unaided eye is called it's what?
Apparent magnitude.
What is an astrometer?
An astrometer is a device designed to measure the brightness, relation, or apparent magnitude of stars.
What does measurement of the brightness of a star call?
Brightness of stars (apparent and absolute magnitude) is measured by convention, taking an another star as a standard.
What is similarities between apparent brightness and absolute brightness?
Both relate to brightness; both are measured in the same units; both are used for astronomical objects such as stars or galaxies.
