Do you mean Stellar Magnitude or do you mean how big some measurement is?

Magnitude usually means the measure of smething,

For example if something is 7 meters away from the "origin" the magnithude of its distance is 7

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.


Explain a stars 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 suns absolute magnitude from earth?

You cannot ask for an absolute magnitude and specify the distance, as the absolute magnitude is derived from a set distance of 32.616 light years.At that distance, the absolute magnitude of the Sun is +4.83From Earth the apparent magnitude -26.74


Is a star's absolute magnitude dependent on its distance from the observer?

No, a star's absolute magnitude is a measure of its intrinsic brightness regardless of its distance from the observer. It is a standardized measure that allows for comparison of the brightness of stars at a set 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 from the Earth. The apparent magnitude of a star is how bright it appears from Earth, while the absolute magnitude is how bright a star would be if it were located at a standard distance of 10 parsecs away from Earth. The difference in magnitude is primarily influenced by the star's distance, with closer stars having a smaller difference and more distant stars having a larger difference between their apparent and absolute magnitude.

Can Distance be fully described with a magnitude and a unit?

Distance can be fully described with a magnitude and a unit. It is a scalar quantity, which means it has a magnitude (numerical value) but not a direction. A related quantity is displacement, which is the straight line distance from a starting point to an ending point. Displacement is a vector quantity, so it can only be fully described with a magnitude, a unit, and and direction.


How are distance and displacement different?

Distance is the total length of the path traveled by an object, while displacement is the change in position of the object from its initial point to its final point. Distance is a scalar quantity, only having magnitude, while displacement is a vector quantity that includes both magnitude and direction.


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.


Which measure is not considered when measuring absolute magnitude?

Distance. Absolute magnitude is a measure of the intrinsic brightness of a star, independent of its distance from Earth.


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 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 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 is the relation between magnitude of distance and displacement?

-- Distance is a scalar quantity, whereas displacement is a vector. -- Distance is the integral of magnitude of displacement. -- Magnitude of displacement is always less than or equal to distance. -- The two quantities are equal when the motion is in a straight line.


What is the magnitude of a star if all stars were the same distance from earth?

Absolute magnitude


When does distance traveled equal the magnitude of displacement vector?

Distance traveled is equal to the magnitude of the displacement vector when the motion is in a straight line.
