Astronomers define star brightness in terms of apparent magnitude how bright the star appears from Earth and absolute magnitude how bright the star appears at a standard distance of 32.6 light-years, or 10 parsecs.
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.
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 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 is an apparent brightness?
An apparent brightness is the brightness of a star as measured by an observer.
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 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
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.
