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.
What are the relationships between apparent magnitude and absolute magnitude?
Apparent magnitude is the brightness of an object as seen from Earth without any atmosphere.Absolute magnitude is the brightness of an object as seen from a predetermined distance, depending on the object.For planets, the distance used is 1 AU (Astronomical Units). Stars and galaxies use 10 parsecs which is about 32.616 light years.The dimmer an object is the higher the positive value. The brighter an object is the higher the negative value.Examples:The Sun has an apparent magnitude of -26.74 but an absolute magnitude of 4.83Sirius has an apparent magnitude of -1.46 but an absolute magnitude of -1.42This means that from Earth, the Sun is a lot brighter, but if the Sun was replaced by Sirius, Sirius would be 25 times more luminous.See related links for more information
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.
How bright is Arcturus?
Arcturus has an absolute magnitude of -0.29 and an apparent magnitude of -0.04
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.
How bright was the brightest supernova in the universe?
As of January 2016 the brightest supernova reported was ASSN SN 15lh. It had an absolute magnitude of - 23.5. For comparison, the absolute magnitude of the Sun is 4.83.
What is a synonym for absolute magnitude and apparent magnitude?
Apparent magnitude: How bright something looks to us. Absolute magnitude: How bright something really is - expressed as the apparent magnitude it would have at a standard distance.
Is the brightness of a star compared to other stars called its magnitude.?
No; the "magnitude" is how bright the star is. It can either mean:* The apparent magnitude = how bright it seems to us, * The absolute magnitude = how bright the star really is (i.e., how bright it would seem at a standard distance).
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.
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.

What determines absolute magnitude?
How bright the object would be if it was the same distance from Earth as the sun is
What is a star's absolute brightness?
That means how bright the star really is. The "absolute magnitude" is defined as how bright the star would look if it were at a standard distance from us.
Are absolute magnitude and apprent magnitude the same thing?
No, absolute magnitude and apparent magnitude are not the same thing. Apparent magnitude is a measure of how bright an object appears from Earth, taking into account its distance and intrinsic brightness. Absolute magnitude, on the other hand, is a measure of how bright an object would appear if it were located at a standard distance of 10 parsecs (32.6 light-years) away from Earth.
