What is the difference between apparent magnitude and surface magnitude?
The two types are apparent magnitude, the magnitude of a star as it appears to us, and absolute magnitude, which is what a star's apparent magnitude would be at a standard distance of ten parsecs.
What terms takes into consideration the brightness of a star but ignores the differences that distance can make?
"Apparent magnitude" is the star's brightness after the effects of distance. "Absolute magnitude" is the star's brightness at a standard distance.
What distance is the absolute magnitude and the apparent magnitude of a star would be equal if the star is seen at?
The standard distance is 10 parsecs. At this distance the star's apparent magnitude equals its absolute magnitude. A star 100 parsecs away has an absolute magnitude 5 magnitudes brighter than its apparent magnitude. 1 parsec is 3.26 light-years.
Is the star's apparent magnitude the intrinsic property of a star?
No. Absolute magnitude is an intrinsic property of the star, but apparent magnitude also depends on the star's distance from Earth.
What magnitude of a star is how bright it would be at a distance of 32.6 light years from earth?
That is called the absolute magnitude. It is a measure of the star's real brightness. Apart from the distance (10 parsec), another (implicit) assumption is that there is nothing in between that reduces the star's light.
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 three factors determine the magnitude of star?
The apparent magnitude of a star is dependent on the star's size, temperature and distance from where it is observed. An absolute magnitude is determined by the same three factors, but the distance is fixed at 10 parsecs.
What is the magnitude of a star if all stars were the same distance from earth?
Absolute magnitude
A star might be much brighter than it appears to be This is called the star's absolute magnitude The difference in apparent magnitude and absolute magnitude is due primarily to the star's?
Distance
A star might be much brighter than it appears to be. This is called the star's absolute magnitude. The difference in apparent magnitude and absolute magnitude is due primarily to the star's -?
Distance
Is a star's absolute magnitude dependent on its distance from the observer?
Absolute magnitude is based on an observer being at the same distance from any star.Apparent magnitude is based on the brightness of a star from Earth without any atmosphere.
What the relationship between magnitude and size of the star?
The brightness of a star depends on its temperature, size and distance from the earth. The measure of a star's brightness is called its magnitude. Bright stars are first magnitude stars. Second magnitude stars are dimmer. The larger the magnitude number, the dimmer is the star.The magnitude of stars may be apparent or absolute.
