This is the brightness a comet would exhibit if placed 1 AU from both the Earth and sun. Using a special formula, the brightness estimates made for comets can be converted to absolute magnitudes which aids in the study of how a comet reacts as it approaches or recedes from the sun. For H0, an accompanying value designated "n" determines how fast a comet brightens or fades when approaching or receding from the sun.
A number specifying the brightness that a star would have if viewed from a distance of 10 parsecs. Because this is a fixed distance, it is a measure of the star's intrinsic, or actual, brightness. Also see, Apparent Magnitude.
(astronomy) the magnitude that a star would have if it were viewed from a distance of 10 parsecs (32.62 light years) from the earth
The magnitude a star would appear to have if at a distance of 10 parsecs from Earth. Absolute magnitude is a measure of a star's intrinsic luminosity and allows us to directly compare stars.
the true brightness of a star based on its actual luminosity, or light output.
The apparent magnitude that an object would possess it if was placed at a distance of 10 parsecs from the observer. In this way, absolute magnitude provides a direct comparison of the brightness of stars.
Apparent magnitude is a scale which measures how bright stars appear to be. However, a more distant star could actually be brighter than a closer one, and yet because of the difference in distances, the brighter star may appear dimmer. The system of absolute magnitude is defined such that the value is that which a star would give, if it were at a distance of 10 parsecs. This measure is one of the actual brightness of a star. The absolute magnitude with the apparent magnitude can be used to calculate the distance to a star.
a measure of how bright a star would be if all stars were the same distance from Earth
The absolute magnitude Mvis of an astronomical object is the apparent magnitude an object would have if it were placed at a distance of 10 Parsec from the viewpoint. This magnitude is given as order of magnitude.
The apparent brightness of a celestial object when observed at some standard distance. The absolute magnitude of a star is its apparent brightness at a distance of ten parsecs. The absolute magnitude of a Solar System object is its apparent brightness at a distance on one astronomical unit.
the apparent brightness an object would have if it were 10 parsecs (32.6 light-years) from Earth
The apparent magnitude of a star at 32.6 light-years (10 parsecs) away.
( ) - The Relative brightness of each star by comparing them if they were all the same distance away at 10 parsec ( 32.6 light years ) = +5 -5 Log ( 1 / Parallax ). Also see Apparent Magnitude.
The apparent brightness—or magnitude—a star would have if it were 10 parsecs (32.6 light-years) from Earth. It is used to compare the true, intrinsic brightnesses of stars. The Sun has an absolute magnitude of +4.8.
The apparent magnitude a star would have if it were placed at a standard distance of 10 parsecs from Earth.
The apparent magnitude an object would have if placed at a distance of exactly 10 parsecs (=32.6 light years supergiant star might have an absolute magnitude of -8 whereas a dim red dwarf might have an absolute magnitude of +16. The Sun has an absolute magnitude of +4.8 - about half way between the two extremes.
A measure of the inherent brightness of a star independent of any observer. Equivalent to the apparent magnitude of a star seen from a distance of 10 parsecs.
The apparent magnitude that a star would possess it if were placed at a distance of 10 parsecs from Earth (32.6 light years). In this way, absolute magnitude provides a direct comparison of the brightness of stars. The apparent magnitude of a star is based upon its luminosity and its distance. If all stars were placed at the same distance then their apparent magnitudes would only be dependent on their luminosities. Thus, absolute magnitudes are true indicators of the amount of light each star emits.
The magnitude that a celestial object would appear to have at a distance of 10 parsecs. i.e. it is independent of the actual distance from us obversers on earth. See also: Magnitude
The brightness a star would have if located away 10 parsecs from the Earth.
The apparent magnitude that a given star would have if that star were placed 10 parsecs, or 32.6 light years, away from an observer. Absolute magnitude is a measure of the intrinsic brightness of an object. See also: parsec, star
The stellar magnitude any meteor would have if placed in the observer's zenith at a height of 100 km.
the brightness of an object that would be measured by an observer if the object was 10 parsecs away. It is a measure of the object's luminosity.
The magnitude a star would seem to have if viewed from a standard distance of 10 parsecs (32.6 light years).
In astronomy, absolute magnitude is the apparent magnitude, m, an object would have if it were at a standard luminosity distance away from us, in the absence of interstellar extinction. It allows the overall brightnesses of objects to be compared without regard to distance.
