The absolute magnitude of a star is not affected by its distance from Earth, its spectral type, or its position in the galaxy. Instead, it is a measure of the star's intrinsic brightness, specifically how bright it would appear at a standard distance of 10 parsecs. Factors like the star’s age or its surrounding environment also do not influence its absolute magnitude.
What else can I help you with?
What is difference in a star's apparent magnitude and absolute magnitude caused by?
How far away the star is.
What is the absolute magnitude of this star m equals 6?
The absolute magnitude of a star is a measure of its true brightness if it were placed at a standard distance of 10 parsecs from Earth. To calculate the absolute magnitude from the apparent magnitude (m) of 6, you would need to know the star's distance. Without this information, we cannot determine the absolute magnitude.
Explain why size is the only factor that determines the stars absolute magnitude?
The absolute magnitude is a measure of the star's luminosity hence the smaller the size the less the absolute magnitude.
How will a star bright if it was near the sun?
A star near the Sun might be brighter or dimmer, it depends on how big it is. Each star has an absolute magnitude and if you find out a star's absolute magnitude, and then subtract 31.4, that would be its visual magnitude at the Sun's distance from us.
What are three factors that determine the apparent magnitude of a star?
Its real (absolute) magnitude; its distance from Earth; the amount of light that's absorbed by matter between the star and us (extinction); distortions due to gravitational lensing.
What 2 factors determine a star's apparent magnitude?
There are three factors, actually. The star's size and temperature determine the absolute magnitude, or how bright the star really is. Those two factors can be considered as one - the star's absolute magnitude. The absolute magnitude combined with our distance from the star determines its apparent magnitude, or how bright the star appears to be from Earth. So, a big, hot, super bright star very far away may have the same apparent magnitude as a small, cool star that's fairly close to the Earth.
How does a star's temperature affect its absolute magnitude?
The absolute magnitude of a start will increase both:* If its surface temperature increases, and * If its diameter increases.
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.
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 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
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.
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.
