Our Sun is pretty much average. It's larger than about 60 to 70 % of the other stars in the Milky Way; the estimate increases as we keep discovering more and more very small and very dim brown dwarf "stars" (that are right on the boundary between "star" and "not star").
Astronomers define star brightness in terms of apparent magnitude (how bright the star appears from Earth) and absolute magnitude (how bright the star appears at a standard distance of 32.6 light years, or 10 parsecs).
movies you watch, books you read you absolute idiot!
A magnitude comparator is an electronic circuit used to compare two binary numbers and determine their relative sizes. It outputs signals indicating whether one number is greater than, less than, or equal to the other. This functionality is essential in digital systems for decision-making processes, sorting operations, and various arithmetic functions. Magnitude comparators are commonly used in applications such as digital signal processing and microprocessor design.
GaAs has high mobility compare to Si
In equatorial regions the water is warm, therefor the temperature will be higher. The temperature of t he polar regions will be less than the equatorial region because the water density is less.
I assume when you mean brightness, you mean apparent magnitude as opposed to absolute magnitude. The quasar 3C 273 has an apparent magnitude of about 12.8 whereas the brightest galaxy - the Large Magellanic Cloud has an apparent magnitude of 0.9. However, in absolute magnitudes, 3C 273 has an absolute magnitude of about -26.7 very similar to our own Sun.
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.
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.
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.
The apparent magnitude is what we see, and this can be measured directly. The absolute magnitude must be calculated, mainly on the basis of (1) the apparent magnitude, and (2) the star's distance. So, to calculate the absolute magnitude, you must first know the star's distance.
Astronomers define star brightness in terms of apparent magnitude (how bright the star appears from Earth) and absolute magnitude (how bright the star appears at a standard distance of 32.6 light years, or 10 parsecs).
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
You can compare their magnitude (absolute values) but not the numbers themselves.
Does it mean that the star is a main sequesnce star? ( . Y . ) The above isn't true. A star can be a blue supergiant and be on the main sequence but still not be even visible to us, therefore the apparent and absolute magnitude wouldn't be the same. But to answer your question, I don't think it has a name, it just means that you are seeing the star's absolute and apparent magnitude at the same time, so if you placed the star at 32.6 light years away(the absolute magnitude scale)then the star would not appear to change in brightness
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.
The brightness of a star is usually referred to as its magnitude. Every star has two magnitudes. The apparent magnitude is how bright it appears to us here on earth. The absolute magnitude is the apparent magnitude that the star would have, if it were viewed from a standard distance. The apparent magnitude of our sun is vastly greater than that of any other celestial object. In terms of absolute magnitude, our sun can't begin to compare with some of the big bright stars in the universe.
