The distance from the earth to a star that has identical apparent and absolute magnitudes is?
The standard distance used for evaluating absolute magnitude is 10 parsec.The standard distance used for evaluating absolute magnitude is 10 parsec.The standard distance used for evaluating absolute magnitude is 10 parsec.The standard distance used for evaluating absolute magnitude is 10 parsec.
Why is absolute magnitude stars used in the HR diagram?
The equation for the magnitude of a star is; M=m-5log(d/10) where:M - Absolute magnitude (The brightness of a star viewed 10 parsecs away)m - Apparent magnitude (The brightness of a star as viewed from Earth)d - Distance from the star (Pc)
What factor affects the absolute brightness of a star?
Energy output, as absolute brightness (magnitude) is taken at a standard distance of 10 parsecs.
How bright is a star which is actually at a distance of 32.6 light years away from earth called?
THat is called the star's absolute magnitude. The standard distance is 10 parsecs.THat is called the star's absolute magnitude.

What is the magnitude of the red giant star?
a red giant star is a luminous star having mass between 0.5 to 10 solar masses and absolute magnitude +10 according to hertzsprung Russell diagram And have spectral type k And m
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.
What is apparent and absolute magnitude?
Apparent magnitude is the measure of how bright a star appears to be from our vantage point. Absolute magnitude is the measure of how bright a star would be if it were located 10 parsecs from earth.

Why is the absolute magnitude of some stars greater their apparent magnitude?
The apparent magnitude is how bright the star appears to us, but stars are all at different distances so that a star that is really bright might look dim because it is very far away. So the absolute magnitude measures how bright the star would look if it was placed at a standard distance of 10 parsecs. When the absolute magnitude is greater than the apparent magnitude, it just means that it is closer than 10 pc. The brightest stars have absolute magnitudes around -7.
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.
Why is absolute magnitude stars used in the HR diagram?
The equation for the magnitude of a star is; M=m-5log(d/10) where:M - Absolute magnitude (The brightness of a star viewed 10 parsecs away)m - Apparent magnitude (The brightness of a star as viewed from Earth)d - Distance from the star (Pc)
What kind of star has an absolute magnitude of 10 and a surface temperature of 20000 K?
white dwarf.
What is the definition of absolute magnitude?
The absolute magnitude is the magnitude (brightness) an object would have at a standard distance - how bright would it look at a standard distance. For a star or galaxy, the standard distance of 10 parsecs is commonly used.
What factor affects the absolute brightness of a star?
Energy output, as absolute brightness (magnitude) is taken at a standard distance of 10 parsecs.

How bright is a star really is?
We use the phrase "absolute magnitude" to describe how bright a star really is, and "apparent magnitude" to describe how bright it looks from Earth. The lower the number, the brighter the star. Like the Richter scale of earthquakes, the scale is logarithmic; a change of "1" indicates a difference of a factor of 10. For example, the bright red supergiant star Betelgeuse, at the upper left corner of the constellation Orion, has an absolute magnitude of -5.14, and an apparent magnitude of 0.58. Our Sun has an absolute magnitude of 4.83, and an apparent magnitude of -27.6.
