"Atmospheric Perspective" is created because there are tiny particles suspended in the air. Smog, dust, water vapor; all of these particles are too small to see individually, but each one bends or blocks light, however slightly. Over long distances, these tiny things add up and will mute or block the colors (reflected light) of the object you are perceiving in the distance. Your mind makes distance assumptions based on the relative size of the object and the expected contrast (or lack of it) with the horizon and surrounding objects, and how much the object moves in parallax when you change your viewing angle. Fog could be seen as an exaggerated example of this phenomenon.

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.
1: The size of the planet.2: The planet's distance from the Sun.3: The "albedo" of the planet (the percentage of the Sun's light it reflects).If you mean how bright the planet appears to us on Earth, then the distance from Earth is obviously very important.
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)
The numeric value of the apparent magnitude would increase, since bright objects have lower magnitude values than dim objects.To give some actual numbers as an example: the Sun has an apparent magnitude of about -27. It is much, much brighter than the moon, which at its brightest has an apparent magnitude of -13 or so.
apparent magnitude (brightness of a star when viewed from Earth) depends on the size of the star, how hot it is, and its distance from Earth
A star's brightness at a standard distance is referred to as its apparent magnitude. This standard distance is 10 parsecs (32.6 light-years) from Earth. Apparent magnitude allows astronomers to compare the brightness of stars as seen from Earth, regardless of their actual distance from us.
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.
No. Absolute magnitude is an intrinsic property of the star, but apparent magnitude also depends on the star's distance from Earth.
Apparent magnitude is a measure of how bright a star appears from Earth, taking into account its distance and how much light it emits. Absolute magnitude, on the other hand, is a measure of a star's intrinsic brightness if it were observed from a standard distance of 10 parsecs. It helps in comparing the true brightness of stars regardless of their distance from Earth.
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.
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.
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
The Sun has an absolute magnitude of about 4.8 and an apparent (visual) magnitude of around -26.7. It's roughly 150,000,000 km from Earth on average.
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.
