What is the apparent magnitude of the star Deneb?
The apparent magnitude of Deneb is +1.25, a fairly bright bright star from Earth.
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).
Does apparent magnitude refer to real luminosity?
No. Apparent magnitude (or luminosity) means how bright a star (or other object) looks to us; absolute magnitude (or luminosity) refers to how bright it really is.
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.
What is a bright star -5 or 5?
A star with apparent visual magnitude of -5, if there were any, would appear ten magnitudes brighter than (about 2,154 times as bright as) one with apparent visual magnitude of +5.
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).
What is the apparent magnitude of the star Deneb?
The apparent magnitude of Deneb is +1.25, a fairly bright bright star from Earth.
How bright a star appears as seen earth is called?
Apparent magnitude is the measure of how bright a star appears as seen from Earth. This scale is based on a star's brightness perceived by human observers. The lower the apparent magnitude, the brighter the star appears.
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 can apparent magnitude be a misleading number?
Apparent magnitude can be a misleading number because they do not necessarily correspond with the actual brightness of the star. The apparent magnitude is the number given to a star based on how bright it looks.
What the relationship between magnitude and size of the star?
The brightness of a star depends on its temperature, size and distance from the earth. The measure of a star's brightness is called its magnitude. Bright stars are first magnitude stars. Second magnitude stars are dimmer. The larger the magnitude number, the dimmer is the star.The magnitude of stars may be apparent or absolute.
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).

How bright a star appears as seen from earths is called?
The apparent magnitude.
How bright a star is as seen from earth is called?
This is called "Apparent Magnitude".
What is different shape between apparent and absolute magnitude of stars?
This has nothing to do with shape. The apparent magnitude means how bright a star looks to us. The absolute magnitude means how bright the star really is (expressed as: how bright would it look at a standard distance).
