Sun's apparent visual magnitude: - 26.7
Full moon's apparent visual magnitude: - 12.6
Difference: The sun is 14.1 magnitudes brighter than the full moon. (Brightness ratio of 50,120)
The apparent magnitude of a celestial object is a measure of its brightness as seen from Earth. The lower the apparent magnitude, the brighter the object appears in the sky. This means that a celestial object with a lower apparent magnitude is brighter than one with a higher apparent magnitude.
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.
An object that is ten thousand times brighter than Rigel would have an apparent magnitude of about -6. Rigel has an apparent magnitude of about 0.1, so an object that is ten thousand times brighter would be much more luminous and appear as a very bright object in the night sky.
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.
Apparent magnitude is a measure of how bright a celestial object appears from Earth. It is a logarithmic scale where lower numbers indicate brighter objects. Apparent magnitude takes into account the intrinsic brightness of the object as well as its distance from Earth.

Yes, but only if the conditions are right. 51 Pegasi has an apparent magnitude [See Link] of 5.49. The faintest object the naked eye can see, has an apparent magnitude of 6.5 (in perfect conditions). Even with binoculars, the faintest object is 9.5. The larger the apparent magnitude, the dimmer the object is. Our Sun has an apparent magnitude of -26.73 (yes minus)
It means "apparent" - visible to the naked eye. It is the magnitude of an object as viewed from Earth. The Sun has an apparent magnitude of -26.73 because it is very close to us. However, Sirius, which is actually more luminous, has an apparent magnitude of -1.46 because it is further away from Earth. For this reason we also use absolute magnitude, which is the luminosity of an object at the same distance. Using absolute scales. The Sun has a value of 4.85 and Sirius has a value of 1.42. (NB: The lower the value, the more luminous an object is)
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.
Apparent magnitude is the brightness of a celestial object as seen from Earth, taking into account distance and extinction from the atmosphere. Absolute magnitude measures the intrinsic brightness of a celestial object if it were placed at a standard distance of 10 parsecs (about 32.6 light-years) away from Earth. In essence, apparent magnitude is how bright an object appears from Earth, while absolute magnitude is how bright it would be at a standardized distance.
Absolute magnitude and apparent magnitude are the same because they are both ways on how to measure the brightness of a star. Absolute magnitude is how bright is the star if we will see it in a 32.616 light-years distance while apparent magnitude is the brightness of it that we see on Earth.
The sun's apparent visual magnitude is listed as -26.74.When you say the "greatest apparent magnitude", I take that to mean thedimmest object that the naked eye can detect in good seeing conditions.It varies among individuals and their eyes, but the figure of 6th magnitudeis usually considered the benchmark limit for the general population.So that's a span of 32.74 magnitudes, or a brightness ratio of 1.247 x 1013 .Do you hear that ? That's saying that the sun is 12,473,835,000,000 times as brightas the dimmest thing that your eye can see in the night sky. Now that's bright!(Engineering alert: That's almost exactly 131 dB ... the difference between1 nanowatt and 12,474 watts.)
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.
The sun has the greatest apparent magnitude in the sky because it is the closest star to Earth, making it appear very bright. Its proximity combined with its luminosity contribute to its high apparent magnitude compared to other celestial objects.
An object that is ten thousand times brighter than Rigel would have an apparent magnitude of about -6. Rigel has an apparent magnitude of about 0.1, so an object that is ten thousand times brighter would be much more luminous and appear as a very bright object in the night sky.
