What is the magnitude of Perseus' brightest star?
Alpha Persei (Mirfak or Algenib) is the brightest star in the constellation of Perseus.It has an apparent magnitude of 1.79 and an absolute magnitude of -4.50
What is the absolute magnitude of Altiar?
The star is called Altair; the absolute magnitude is estimated at 2.21.The star is called Altair; the absolute magnitude is estimated at 2.21.The star is called Altair; the absolute magnitude is estimated at 2.21.The star is called Altair; the absolute magnitude is estimated at 2.21.
How bright a star actually is at a distance of 32.6 light years away from earth is?
That's the number called the star's "Absolute Magnitude".That is called the star's "absolute magnitude".
How does the apparent-magnituede of a star differ from it absolute magnitude?
Absolute magnitude is how bright a star is. Apparent magnitude is how bright it looks to us (on Earth).
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
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 difference in a star's apparent magnitude and absolute magnitude caused by?
How far away the star is.
What is the color of the star Mirfak?
Mirfak, also known as Alpha Persei, is a blue-white star.
How bright a star actually is a distance of 32.6 light years from earth is called?
That's called the star's absolute magnitude.
Does the absolute magnitude of the sun show that it is the brightest star?
No. The sun has an absolute magnitude of 4.83. By comparison, Betelgeuse has an absolute magnitude of -5.85. Lower numbers indicate a brighter star. In this case Betelgeuse is actually several thousand times brighter than the sun. The sun is the brightest star as measure by apparent magnitude, which is how bright a star looks from a given location and depends on both absolute magnitude and distance.
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.
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.
